"We're fighting, aren't we? The message said Harry was back, and we were going to fight! I'll have to get a wand, though..."
—Dean before the Battle of Hogwarts[src]

Dean Thomas was a half-blood wizard, the son of a wizard and a Muggle.[1] His father left his mother when he was young, and his mother married another man, giving Dean several half-siblings.[1] Dean grew up thinking he was Muggle-born, because his father never told his mother that he was a wizard, and was eventually murdered by Death Eaters when he refused to join them.[1] Dean was a Gryffindor student at Hogwarts School of Witchcraft and Wizardry, played as a Chaser for their Quidditch team for a time.

In his fifth year, he joined Dumbledore's Army, an organisation founded and led by Harry Potter. He was also the best friend of Seamus Finnigan, and dated Ginny Weasley for a time. Dean, although a half-blood, could not prove that he had any wizarding heritage, and was therefore in danger when Lord Voldemort took control of the Ministry of Magic in 1997. Dean was forced to go on the run to avoid arrest and imprisonment by the Muggle-Born Registration Commission, missing his seventh year of schooling. He was eventually captured by Snatchers, but escaped Malfoy Manor along with several other prisoners and soon returned to Hogwarts to participate in the final battle of the Second Wizarding War.


Early lifeEdit

Dirk Cresswell: "Muggle-born, eh?"
Dean: "Not sure. My dad left my mum when I was a kid. I’ve got no proof he was a wizard, though."
— Dean on his heritage in 1997[src]

Dean is the son of a wizard father and a Muggle mother, though he believed he was Muggle-born when he went to Hogwarts.[1] His father left when Dean was very young, never telling his wife that he was a wizard, out of the belief that not knowing the truth would protect her and their son from the potential dangers of the First Wizarding War.[1] Dean's father was later killed by a group of Death Eaters when he refused to join them.[1]

Dean's mother later remarried a Muggle, Mr. Thomas, who raised Dean as his own son.[1] Dean lived with several half-siblings, who are implied to all be female, in London.[1][3] He had a "very happy home life."[1] He was a supporter of the West Ham football team, and was very artistic and showed off his talent throughout his school career. All of Dean's half-siblings were non-magical.

Education at HogwartsEdit

First yearEdit

Ron: "It's not football, Dean, you can't send people off in Quidditch, and what's a red card?"
— Dean Thomas and Ron Weasley discussing Marcus Flint's move against Harry Potter[src]
File:Dean Thomas.jpg

The arrival of a letter for Dean from Hogwarts caused Mrs. Thomas to suspect that Dean's biological father may have been a wizard, which he was. However, she never had proof of this, and so Dean was believed to be Muggle-born.[1] Dean started his education at Hogwarts School of Witchcraft and Wizardry on 1 September, 1991 and during the Welcoming Feast he was Sorted into the house of Gryffindor, where he met with fellow Gryffindor Seamus Finnigan. Dean shared a dormitory with Seamus who soon became his best friend, as well as Neville Longbottom, Ron Weasley and Harry Potter, with whom he later became good friends.[4] Due to his muggle upbringing, Dean, like Harry, was not a supporter of Quidditch as he had never heard of the sport (though he would eventually become quite a skilled player, filling in for Katie Bell in his sixth year). However, he hung a West Ham football team poster above his bed, much to the bemusement of Ron, who could not believe Dean would find a game with only one ball, two goals, and where no one was allowed to fly, interesting, prodding the poster in an attempt to get the football players to move.

Dean, being artistic, drew a banner entitled "Potter for President" for his dormmate Harry Potter during the latter's first Quidditch match. The poster pictured a realistically painted Gryffindor lion that, due to Hermione Granger's enchantment, changed colours throughout the game. When Harry was fouled by Marcus Flint, Dean demanded that the referee send Flint off (with a Red Card), and Ron Weasley explained that in Quidditch that does not happen, which Dean, having a Muggle upbringing, was unaware of.


Second yearEdit

Parvati: "But, Professor, you'd probably have to use Dark Magic to open it-"
Binns: "Just because a wizard doesn't use Dark Magic, doesn't mean he can't, Miss Pennyfeather, I repeat, if the likes of Dumbledore-"
Dean: "But maybe you've got be related to Slytherin, so Dumbledore couldn't-"
— Dean Thomas correctly speculates about the Chamber of Secrets[src]

In his second year, Dean Thomas joined the Duelling Club, a precautional club taught by Gilderoy Lockhart in an attempt to train students in battle against any possible danger that may be lurking around Hogwarts. He among other students shared their speculation about the Chamber of Secrets and what might be inside and how to get in. Dean is about to make a correct speculation but Professor Binns cuts him short before he can finish. Dean was believed to be at risk of being attacked as he was a presumed Muggle-born and Muggle-born students were being attacked through the year.

Third yearEdit


In Dean's third year, he would have been now allowed to visit the village of Hogsmeade, and he expressed positive interest in the new Care of Magical Creatures teacher Rubeus Hagrid as he always got on with him. However, in their first lesson when Hagrid introduced the class to a Hippogriff named Buckbeak, Dean stepped back and showed fear when Hagrid asked for a volunteer to pet him. Also in this year Dean would take on the subject Divination and was, along with Lavender Brown, one of the few students in their class unfamiliar with the Grim[5]. That year, Hogwarts became under the protection of Dementors following the hysteria surrounding the Azkaban escape by Sirius Black.


Fourth yearEdit

During Dean's fourth year, Hogwarts hosted the Triwizard Tournament, and his friend, Harry Potter had qualified as an underaged champion. This was against tournament rules, so Harry was not the popular choice for Hogwarts representative, and instead most support was given to Cedric Diggory by Dean's peers. However Dean supported Harry throughout the course of the tournament, and was loyal to his friend.

Dean would also be allowed to attend the Yule Ball as part of the tournament traditions. He commented that Harry and Ron were lucky to get the prettiest girls in the year as their dates, twin sisters Parvati and Padma Patil; it is unknown who Dean attended the dance with, as his best friend Seamus Finnigan was going with Lavender Brown and Neville was going with Ginny Weasley.

Later on in the tournament, after Ron Weasley had forgiven Harry, Dean also seemed to be more supportive. After the third and final task, Harry returned back to Hogwarts with Cedric Diggory's dead body, and he said that Lord Voldemort was at large again. Albus Dumbledore took this information and at the end of the year he gathered students for a Memorial Feast to Cedric Diggory in which he told them about the events that took place during the third task.

Fifth yearEdit

File:Dean-in-OotP-dean-thomas-alfie-enoch-647082 428 285.jpg
Dean: "It's like Harry said, isn't it? If we're going to be attacked, it won't be risk free."
Umbridge: "I repeat, do you expect to be attacked during my classes?"
— Dean Thomas argues with Umbridge[src]

During Dean's fifth year, Dolores Umbridge was appointed to Hogwarts school to act as the "eyes of the Minister." Dolores Umbridge did not get along well with Dean; during her first lesson they argued openly about their opinions on the teaching methods at Hogwarts. She called Remus Lupin a "dangerous half-breed," which caused Dean to jump in to his defence, claiming that he was the best teacher he ever had, and commenting in response to Umbridge's comments that her predecessor had actually performed curses on them that the man in question had "turned out to be a maniac", although he noted that they had still learned a great deal. He also was very supportive of Harry's claims that Voldemort had returned.


She eventually caused an uproar amongst the students, and when it came time to fight back, Dean was one of the first to arrive for the inaugural meeting of the group that became Dumbledore's Army in 1995, and his support for his friends does not appear to have faltered, even though Seamus, his best friend, initially believed the smear campaign the Daily Prophet launched against Harry and Albus Dumbledore over their claims that Lord Voldemort had returned.

Also that year, Dean accidentally insulted his new Divination teacher, Firenze, after Umbridge sacked Sybill Trelawney. Firenze was telling Dean that he had been banished by his herd living in the Forbidden Forest and Dean was excited to discover there were more centaurs around the school grounds and asked him if Hagrid was breeding them. Firenze told Dean that centaurs were their own race and had little to do with humans and did not require their help to breed, which caused Dean to become extremely embarrassed.


During his fifth year, Dean took his O.W.L. exams, and after he finished, he was pleased to hear that the results would not arrive until sometime in July, meaning he did not have to worry about them until the middle of the school holidays. Later in the year, Umbridge and her Inquisitorial Squad would discover the D.A. and the meeting would end for the year. Some time around the end of his fifth year, Dean became romantically involved with Ginny Weasley[6] and the two continued dating well into his sixth year.

Sixth yearEdit

Ron: "Just choose someone - better - next time."
Ginny: "Well, I've chosen Dean Thomas, would you say he's better?"
— Ginny announces her relationship to her brother.[src]

In his sixth year, Dean replaced Katie Bell as the Chaser for the Gryffindor Quidditch team after she was hospitalised for touching a cursed necklace. At first, Dean's relationship with Ginny which continued into his sixth year seemed to be strong, as the couple spent a lot of time together, in spite of her brother's disapproval, but their relationship started to spiral downwards. Ginny had started re-developing a crush on Harry Potter (like she did in her first year at school) and she soon became angry with Dean after he laughed when Harry was hit by a Bludger during a Quidditch game. As a result, Dean became overly solicitous with her, trying not to provoke another argument, to keep their relationship going, which increasingly annoyed Ginny.

File:Dean Thomas Slug Club Christmas Party.jpg

According to Hermione Granger, when Harry bumped into Ginny while under his Invisibility Cloak and under the influence of Felix Felicis, Ginny believed that it was Dean who kept trying to help her through the portrait hole, and the two argued over it. Dean stuck to his grounds, saying he did not help her through and Ginny ended their relationship. Dean was shocked at the insensitivity of his friend, Harry, when this happened. Harry and Ginny shared a kiss at a Quidditch party soon after he broke up with her, and Dean broke his glass in astonishment that his room-mate and ex-girlfriend would start a romance so soon. Despite this, Dean shared no hate to either Ginny or Harry for their relationship; he was just hurt they would do such a thing so shortly after he was dumped.

The same year was also the year that the headmaster of Hogwarts school, Albus Dumbledore was killed. Dean Thomas attended his funeral with his best friend Seamus Finnigan after Seamus had rowed rather publicly with his mother to allow him to stay for the ceremony. This would be the last year Dean attended education at Hogwarts School of Witchcraft and Wizardry as the following year he would not return for his own safety. [7]

Second Wizarding WarEdit

Life on the runEdit

"I know Harry Potter. And I reckon he’s the real thing — the Chosen One, or whatever you want to call it."
—Dean to his fellow fugitives whilst on the run[src]

Dean's presumed Muggle-born status put him on the run from the Ministry of Magic in 1997, when it fell under the control of Lord Voldemort and began rounding up Muggle-born wizards and witches, imprisoning them in Azkaban for allegedly stealing magic. This also meant he couldn't return to study his final year of education at Hogwarts as they now had a strict no-muggle-born policy under the influence of new headmaster, Severus Snape.

Dean: "I really do think that Harry Potter..."
Griphook: "Harry Potter, Harry Potter, I'm starting to get sick of your Potter talk!"
Dean: "Alright, but I do think he's our only hope y'know, where are we heading to now?"
— Dean and Griphook talking as they are on the run.[src]

At some point whilst on the run Dean met Ted Tonks, father of Order of the Phoenix member Nymphadora Tonks, and traveled with him, later joining a group of fellow runaways — Muggle-born wizard Dirk Cresswell, and Goblins Griphook and Gornuk. The group stuck together and camped in different areas in an attempt to mislead any trails they may have left. At one point whilst on the run Dean travelled alone with Griphook, Most likely after the others were killed. Dean and Griphook often shared conversations about Harry Potter, Dean fully supporting Harry in his quest and Griphook somewhat doubtful and occasionally finding the mentioning of Harry's name tedious. One evening they were overheard by Harry, Hermione and Ron who where also in hiding; Dean expressed his worry at hearing that his former girlfriend, Ginny Weasley, had gotten into trouble back at Hogwarts, as well as the belief that Harry was fighting Voldemort.

Captured by SnatchersEdit

Harry: "Shh, I can hear someone!"
Dean: "(To Griphook) We're going to walk into Snatchers if we carry on like this"
Hermione: "That sounds like Dean Thomas, but what's he doing out here?"
— The trio over hear Dean talking to Griphook shortly before their capture.[src]
File:Dean griphook 3.jpg

Later, the group of fugitives were found by a group of Snatchers that was led by Fenrir Greyback. Dean and Griphook were the only survivors of the violent capture. Around the same time, Harry Potter triggered the Taboo curse on Voldemort's name, alerting the Snatchers to his location. Ron and Hermione were also captured, as they were with him, and the prisoners were all brought to Malfoy Manor, Death Eater headquarters. All of them but Hermione — who was tortured with the Cruciatus Curse by Bellatrix Lestrange — were imprisoned in the dungeons in the basement, where Luna Lovegood and Mr. Ollivander were already held. Luna had an old nail and used this to cut the ropes binding the group loose and she greeted Dean in a friendly manner. Held down in the basement of Malfoy Manor, the group had to listen helplessly as they overheard Hermione being tortured for information on the levels above.

Rescued by DobbyEdit

Luna Lovegood: "Harry, we want to help you!"
Dean Thomas: "We can't leave you here!"
— Luna and Dean reluctantly leave Harry at Malfoy Manor.[src]

However, the group was soon rescued by Dobby the house-elf, who was fatally injured shortly after successfully transporting them to the home of Bill Weasley and Fleur Delacour, Shell Cottage. Dean helped Harry and Ron dig a grave for Dobby by hand to show gratitude, rather than do it with magic. Dean placed a wooly hat on top of Dobby, to represent that Dobby was a free elf. At the funeral, Dean expressed his thanks to the elf for rescuing them.

Dean spent the next few months of hiding at Shell Cottage with Luna, Griphook and the trio. During this time, Dean and Luna seemed to grow close, despite Dean's bemusement at some of the comments she would make. Mr. Ollivander was able to make Luna a new wand, but Dean was left without one. Harry, Hermione, and Ron were all using wands they had taken at Malfoy Manor, and soon left the cottage with Griphook to break in to Gringotts Wizarding Bank.[8]

Battle of HogwartsEdit

"You haven't got a wand -?!"

In May of 1998, Dean, Luna, Bill, and Fleur received the call to arms from Dumbledore's Army via Dumbledore's Army coins, as Harry, Hermione and Ron had returned to Hogwarts. Despite not even having a wand, Dean returned to Hogwarts. When Dean entered the Room of Requirement, Seamus Finnigan ran forward and hugged him. Dean then fought with his fellow D.A. members in the Battle of Hogwarts, at some point winning himself a wand. During the battle, the trio spotted Dean and Parvati Patil fighting against Antonin Dolohov and stunning other Death Eaters. When Lord Voldemort and all his followers arrived at the castle, Dean stood strong with other loyal members of Dumbledore's Army including Neville Longbottom who killed Nagini.

The Battle of Hogwarts ended with a final duel between Harry Potter and Lord Voldemort which Dean stood amongst the crowd of supporters and witnessed. [8] He also survived the attacks at the end in which Dumbledore's army fought back after Harry's supposed death. After the battle, Dean was seen talking with Seamus and Aberforth Dumbledore.

Later lifeEdit

Dean survived to witness Harry's final defeat of Lord Voldemort and the end of the Second Wizarding War. Not much is known of his later life.

Physical appearanceEdit

Dean's physical description tells him to have dark hair and dark skin and to be even taller than Ron Weasley[9].

Personality and traitsEdit

Umbridge: "You have been exposed to some very irresponsible wizards in this class, very irresponsible indeed - not to mention, extremely dangerous half-breeds."
Dean: "If you mean Professor Lupin, he was the best we ever-"
Umbridge: "Hand, Mr Thomas! As I was saying - you have been introduced to spells that have been complex, inappropriate to your age group and potentially lethal."
— Dean Thomas argues with Umbridge over her being prejudiced[src]

Dean was supportive of Harry Potter during his tough years at Hogwarts.

Dean is very non-prejudiced, so much that when Dolores Umbridge remarked that Remus Lupin was a "filthy half-breed", he jumped in for his defence. Dean was generally an easy-going and good-natured person, able to get along well with many people. For example, he never displayed any anger towards Harry Potter in their sixth year, despite being upset when Harry began dating his ex-girlfriend Ginny Weasley shortly after their break-up[7]. He also easily established a friendship with Luna Lovegood, whom many would consider strange.[8] Dean was also brave and loyal; he was eager to participate in the defence of his school against Death Eaters, despite not even having a wand[8], and never lost his faith in Harry Potter, believing him when he claimed that Lord Voldemort had returned[6], and keeping faith that he would eventually defeat the Dark Lord.

Dean also appeared to be "good with a quill", as in his first year, he drew a "large Gryffindor lion" for the Gryffindor's first quidditch match of the year, and on a "Potter for President" banner he had crafted with the help of Hermione, Neville, Ron and Seamus[4]. In his third year, when Harry was not allowed to go to Hogsmeade because Uncle Vernon had not signed his permission slip, Dean offered to forge Uncle Vernon's signature (Although Hermione pointed out that this offer was pointless from the beginning as Harry had already told the staff that he didn't have a form)[5]. In his fourth year, after Harry completed the Triwizard Tournament's first task, he drew several banners in commemoration, depicting Harry evading the Horntail and some with Cedric Diggory with his head on fire.

Magical abilities and skillsEdit

  • Duellist: Dean proved himself in duelling as he held his own against Antonin Dolohov who was a very skilled Death Eater.
  • Magical skills: The extent of Dean's skills is mostly unknown, but it can be assumed that he is competent in using magic as he doesn't have to be corrected often during class. As a member of Dumbledore's Army it can be assumed he is skilled in Defence Against the Dark Arts.
  • Flying skills: Dean is also a fairly skilled Chaser, as he was Harry's first choice to replace first Katie Bell (who had been cursed) in the match against Slytherin, and then Ginny Weasley (who was substituting as Seeker) in the final match against Ravenclaw.



Dirk Cresswell: "Muggle-born, eh?"
Dean: "Not sure. My dad left my mum when I was a kid. I’ve got no proof he was a wizard, though."
Dirk Cresswell and Dean in 1997.[src]

Little is known about Dean's relationship with his family. His biological father was a wizard who walked out on his Muggle wife and infant son in order to protect them from the Death Eaters. He never told his wife that he was a wizard, and was soon after killed by the Death Eaters when he refused to join their cause. Dean's mother married again a muggle, who raised Dean as if he was his own son. Dean also had several half-siblings, through his stepfather.

Seamus FinniganEdit

File:Seamus FinnigansG.PNG

Dean grew close to Seamus Finnigan, one of his dormmates, during their first year at Hogwarts, and the two remained best friends throughout their school years. The two were often seen together at school, and Dean attended the Quidditch World Cup with Seamus and his mother in 1994. Seamus initially believed the smear campaign the Ministry of Magic and the Daily Prophet ran against Harry Potter when he claimed that Voldemort had returned, but this does not appear to have affected his friendship with Dean, who did believe Harry and who eventually managed to get Seamus to attend the final D.A. meeting of the year.[6]

Seamus was also displeased when Dean was chosen as the replacement Chaser for the Gryffindor Quidditch team over him when Katie Bell was injured, but again, the two still remained best friends.[7] Since Dean could not return to Hogwarts for his final year, the two did not see each other for some time, and they missed each other greatly. When Dean eventually did return to Hogwarts in 1998 to fight in the final battle, Seamus was ecstatic to see him, and ran to hug him.[8]

Ginny WeasleyEdit

File:Ginny Weasley hbp promostills 05.jpg

Dean started dating Ginny Weasley around the end of his fifth year[6]. Ginny's brother and Dean's roommate Ron disapproved of the romance, as demonstrated by his furious reaction to stumbling upon the couple kissing passionately in a deserted hallway. They appeared to be very close at first, but, according to Ginny's friend Hermione Granger, things began to get rocky as Ginny became displeased with Dean for what she perceived as over-protectiveness, as Dean constantly tried to assist her in everything.

Harry contributed to their ultimate break-up by bumping up against Ginny when she and Dean were going through the portrait hole while under his Invisibility Cloak and after having taken Felix Felicis. Thus, luck was on the side of Harry, who had developed an interest in Ginny, and she thought Dean was trying to push her through the portrait. This row led to their split.

Ginny clearly got over Dean soon after they broke up, as she began dating Harry soon after and admitted to him that she had never really given up on Harry. Dean, however, seemed astonished and hurt when he saw Harry and Ginny kissing, and went as far as smashing his glass, indicating that he took their split harder.[7] Later, while Dean was on the run and heard news about Ginny, Harry noted that Dean was concerned for her welfare[8].

Dumbledore's ArmyEdit


Dean became a member of Dumbledore's Army in 1995. He was friendly with the most members of the army. After they were both rescued from Malfoy Manor in 1998, Luna Lovegood and Dean seemed to grow close while staying at Shell Cottage. Dean still seemed rather bemused at some of the odd things Luna said at times, but did not ridicule her, and was seen offering her his hand and helping her in the Room of Requirement just before the Battle of Hogwarts.

Dean was also relatively close to his dormmates Harry Potter, Ron Weasley, and Neville Longbottom, though not to the same extent as with Seamus. Ron spent more time with Dean and Seamus during their fourth year, when he initially believed that Harry had cheated in order to get his name into the Goblet of Fire[10]. Ron very much disapproved when Dean started dating his younger sister, though the two remained friendly[7]. He was also friendly with Hermione Granger, another Gryffindor in his year, who was also the best student of the year.

File:Trio pic.PNG

Dean made a banner for Harry during his first Quidditch match, and believed him about the return of Lord Voldemort in 1995, unlike Seamus, eagerly joining Dumbledore's Army. Harry resented Dean slightly during their 6th year out of jealousy over Dean's romance with Ginny Weasley, on whom he had developed a crush. When Dean and Ginny split up, Harry's enmity lifted, though Dean then became upset when Harry kissed his ex-girlfriend soon after their break-up.[7] In spite of this, Dean never seemed to carry any ill will towards Harry. In fact, during his rescue from Malfoy Manor, he was reluctant to escape with Dobby and leave Harry behind.[8]

Dumbledore's Army

Dumbledore's Army.

Dean was also good friends with both Fred and George Weasley, older Gryffindor students. He helped them in their efforts to sabotage Dolores Umbridge and helped them test Skiving Snackboxes during his fifth year[6].

Other members of Dumbledore's Army are Lee Jordan, Colin and Dennis Creevey, Angelina Johnson, Alicia Spinnet, Katie Bell, Lavender Brown, Parvati and Padma Patil, Ernie Macmillan, Justin Finch-Fletchley, Susan Bones, Hannah Abbott, Zacharias Smith, Cho Chang, Anthony Goldstein, Michael Corner, Terry Boot and Marietta Edgecombe. Dean's relationship with the most of them is unknown.


Dean means "head" or "leader" and is often the title of a department chief at a college or university. Thomas means "twin".

Behind the scenesEdit

  • In the film adaptation of Harry Potter and the Half-Blood Prince, during the Quidditch match, we briefly see Dean playing chaser for Gryffindor (we don't see his last name on the back of his robes, though). In the film, there is no explanation as to why Dean is playing chaser, but it can easily be assumed he is taking Katie Bell's place.
  • During Harry's time in school, Dean is the only male Chaser on the Gryffindor Quidditch Team.
  • In Harry Potter and the Deathly Hallows: Part 1, Dean is not encountered by the trio while on the run and he is not present at Malfoy Manor when the trio are taken there. He is mentioned on radio, but due to his absence in Malfoy Manor it is presumed that he escaped, unlike Griphook.
  • In Pottermore, the early name for Dean Thomas was given with: Gary Thomas. [12]

Character reductionEdit


Dean Thomas was originally going to be a more prominent character in the novels, like Neville Longbottom, Ginny Weasley and Luna Lovegood, but his role was initially cut down. Originally, Dean was called "Gary", and in Harry Potter and the Philosopher's Stone Dean Thomas was going to be first introduced during the "Sorting Hat" chapter. His character was cut from the UK copies due to needing to shorten the chapter, however he still is in some US copies. He also was going to be featured in the chapter "Midnight Duel" going along with Harry, Ron, Hermione, and Neville to confront Draco Malfoy, but he was cut out of this scene entirely. After having cut Dean out so much from the books, Jo did not want him to go unnoticed in the films and when the film version of Harry Potter and the Philosopher's Stone was in production she blew away director Chris Columbus with the amount of information she had on such a minor character. In Harry Potter and the Chamber of Secrets J.K. Rowling had originally included Dean Thomas' background story, which explained about his "Muggle-born" blood status and his father being a wizard, but it was cut out again as it was "unnecessary content". Jo has said that she believes she swapped developing Dean Thomas to develop the character Neville Longbottom instead, as he was more relevant to the overall plot. Dean later plays a somewhat larger role in Harry Potter and the Half-Blood Prince, where he becomes Ginny's boyfriend and a member of the Gryffindor Quidditch team, and Harry Potter and the Deathly Hallows, where he is on the run, kidnapped, and rescued.
