Editing Rupert Giles (section)

===Sunnydale===
At the behest of the [[Watchers' Council]], Giles travels to [[Sunnydale]], [[California]], and works as the [[librarian]] at the local secondary school. There he meets the current [[Slayer (Buffy the Vampire Slayer)|Slayer]], [[Buffy Summers]], whom he begins training. The library, a quasi-command centre for Buffy's demon-hunting gang, sits right above the Hellmouth.

As the [[Watcher (Buffy the Vampire Slayer)|Watcher]], librarian, and general authority figure, Giles often delivers exposition. He is a father figure to Buffy and her friends [[Xander Harris]] and [[Willow Rosenberg]], together forming the "core four" of the Scooby Gang. Giles is often portrayed as something of a "straight man" and his "stuffy" [[Oxford University|Oxford]] sensibility serves as counterpoint to the stereotypical Southern Californian characters and setting. He makes a "weird cluck-cluck sound with his tongue" when he is angry but is "too English to say anything" ("[[Faith, Hope & Trick]]"). He admits to being [[technophobic]], a fact which often brings him into conflict with technopagan and computer science teacher, [[Jenny Calendar]]. However, after Jenny aids him in casting the demon Moloch out of the Internet, the pair reach an understanding and begin a romantic relationship. Despite his obvious fear with modern technology, Giles is quite adept with computers, which is required in his occupation as a librarian (season 3 episode "[[Gingerbread (Buffy the Vampire Slayer)|Gingerbread]]") and likely had received this training while earning his [[master's degree]] in [[library and information science]]. It was never revealed of which library school Giles attended or whether he had pursued his [[Doctor of Philosophy|PhD]] in this field.

In season 2, Giles' dark side is revealed and his relationship with Jenny deepens. In "[[The Dark Age (Buffy the Vampire Slayer)|The Dark Age]]", Ethan Rayne comes to Sunnydale to flee the demon Eyghon. Giles ashamedly admits to Buffy that he was responsible for summoning the demon in his youth, and is horrified when Jenny becomes possessed by Eyghon. Although Eyghon is defeated, Jenny takes time to cope with her ordeal, remaining distant from Giles in the meantime. When new Slayer [[Kendra (Buffy the Vampire Slayer)|Kendra Young]] arrives in Sunnydale, Giles shares with her an appreciation for obscure texts, resulting in Buffy nicknaming her the "She-Giles." Giles feels betrayed when Jenny reveals she is actually a member of the Kalderash gypsy clan, sent to keep an eye on Buffy's relationship with the vampire [[Angel (Buffy the Vampire Slayer)|Angel]]. When Angel loses his soul he reverts to his evil, sadistic alter ego Angelus. Angelus murders Jenny, leaving her corpse for Giles to find in a romantic setting in his apartment ("[[Passion (Buffy the Vampire Slayer)|Passion]]"), Giles seeks revenge by burning down Angelus' base. Angelus later kidnaps and tortures him, and [[Drusilla (Buffy the Vampire Slayer)|Drusilla]] hypnotizes him into thinking she is Jenny so he will reveal how to awake [[Acathla]]. Buffy is forced to kill Angel to save the world, despite Willow's restoring his soul, and subsequently leaves Sunnydale.

In season 3, Giles's paternal feelings for Buffy strengthen significantly. He spends the summer desperately following up every clue as to Buffy's whereabouts, and is overjoyed when she finally returns months later. Giles briefly serves as Watcher for Kendra's replacement Slayer, [[Faith Lehane]]. The Scoobies are given another disturbing glimpse in Giles' past when, along with every other adult in Sunnydale, he reverts to being a teenager by enchanted band candy supplied by Ethan Rayne. He indulges in theft and vandalism, and makes out with and has sex with Buffy's mother, [[Joyce Summers]]. When Buffy keeps Angel's return from hell a secret from the other Scoobies, Giles feels betrayed by her love for the man who tortured him and murdered Jenny, but later agrees to help Angel in "[[Amends]]".

As Buffy's Cruciamentum approaches (a brutal tradition of the [[Watchers' Council]] in which a depowered Slayer is forced to battle a particularly dangerous vampire using only her wits), Giles struggles to cope with the guilt of betraying Buffy's trust. Despite describing the test as "an archaic exercise in cruelty", he secretly injects Buffy with muscle relaxants and adrenaline suppressors, which weaken her significantly, before finally coming clean when the vampire she is meant to fight escapes. Buffy is disgusted, but is later moved when Giles interferes to save her life and is subsequently dismissed for having a father's love for her. Giles is fired, and replaced with [[Wesley Wyndam-Pryce]], but continues to act as Buffy's unofficial Watcher, proving especially helpful when Wesley turns out to be an incompetent coward. When Buffy briefly finds herself endowed with telepathic powers, she 'hears' her mother remembering that Giles was "like a [[stevedore]]" during sex. In a battle with the demonic [[Mayor Richard Wilkins III|Mayor]] of Sunnydale, Giles presses the trigger which destroys the Mayor and [[Sunnydale High]], putting himself out of a job.

In season 4, Giles must cope with unemployment and a growing awareness that Buffy no longer needs him. He continues a sexual relationship with his old friend Olivia. Lacking a sense of purpose, he spends most of his time lounging around his apartment, watching ''[[Passions]]'' with [[Spike (Buffy the Vampire Slayer)|Spike]]. He gets depressed, especially when the Scoobies fail to keep him in the loop regarding Buffy's new boyfriend [[Riley Finn]] and his membership in the Initiative. In the episode "[[Something Blue (Buffy the Vampire Slayer)|Something Blue]]", Giles becomes blind as a result of a faulty spell cast by [[Willow Rosenberg]]. When Ethan Rayne casts a spell on Giles which turns him into a Fyarl demon ("[[A New Man]]"), he must enlist [[Spike (Buffy the Vampire Slayer)|Spike's]] help to escape the Initiative and Buffy, which believes him to be a demon who murdered Giles. Buffy, about to kill him, at the last moment recognizes his eyes and "annoyed" expression, and Ethan is taken into custody by the Initiative. In order to defeat the cyber-demonoid [[Adam (Buffy the Vampire Slayer)|Adam]], Buffy, Willow, Xander and Giles cast a spell to combine their strength. Giles provides the "mind," and Buffy is able to defeat Adam.

At the beginning of season 5, Giles no longer sees his place in Sunnydale and decides to go back to England, telling no one except Willow, whom he needs to organize the research documents for the Scoobies. He quickly abandons this decision when Buffy asks him to be her Watcher again, confessing that she needs him, both emotionally and in order to discover more about what being a Slayer means.

When the owner of The Magic Box is killed by vampires, Giles is convinced by the shop's high profit margins to buy it, hiring Anya as his overly enthusiastic assistant. Buffy learns that her sister, [[Dawn Summers]], is actually the Key: mystical energy disguised in human form to conceal it from the hell-god [[Glorificus|Glory]]. Buffy initially confides only in Giles about Dawn's true nature, and he decides to contact the [[Watchers' Council]] for more information about Glory. In "[[Checkpoint (Buffy the Vampire Slayer)|Checkpoint]]", Quentin Travers tries to coerce Buffy to obey the Council's demands, by threatening to have Giles deported. Buffy stands up to the Council, pointing out that without her there is no need for a Council, and tells them to give her all information concerning Glory and to reinstate Giles as her official Watcher. Travers reluctantly agrees, and leaves.

As the Scoobies labor to find a way to defeat Glory, Giles brings up the difficult idea of killing Dawn to end Glory's plans to take over the world. Buffy vows to protect Dawn at all costs. Glory shares her body with an innocent human named [[Ben (Buffy the Vampire Slayer)|Ben]], and can be killed if Ben dies. In the final battle against Glory, Buffy abandons the fight when Glory turns back into a wounded Ben, so that she can save Dawn. Giles is less merciful. Explaining that Buffy is a hero and therefore different from the rest of humanity, he suffocates Ben with his bare hands ("[[The Gift (Buffy the Vampire Slayer)|The Gift]]").

Season 6 sees Giles reluctantly stepping back to allow Buffy to gain independence. One hundred and forty-seven days after her death, Giles decides to return to England. On the very day he leaves, Willow, Xander, Anya and [[Tara Maclay|Tara]] resurrect Buffy, and he comes back as soon as he hears of this. Despite being overjoyed to have Buffy back, he is furious at Willow for invoking such dark magic, and angrily dismisses her as "a rank, arrogant amateur." While the other Scoobies believe Buffy was in Hell, Giles is not convinced, and his suspicions prove true when [[Once More, with Feeling (Buffy the Vampire Slayer)|a demon's musical spell]] causes Buffy to reveal to them all that she was indeed in Heaven. As Buffy begins to rely excessively on Giles for financial and emotional support, he decides his presence is preventing her assuming responsibility for her life. He leaves again for his native England, moving to a place near [[Bath, Somerset|Bath]], where he works with a powerful local [[coven]].

A few months later, Tara is killed by a stray bullet as [[Warren Mears]] attacks Buffy. Willow, still recovering from an addiction to magic, suffers a relapse, kills Warren and attempts to kill his former partners in crime, before resolving to end humanity's pain (and her own) by destroying the world. Hearing of a dark power rising in Sunnydale, Giles teleports back there, wielding great magical power borrowed from the Devon Coven. As Dark Willow boasts of her indestructibility, Giles knocks her to the floor with a blast of magic energy, saying "I'd like to test that theory" ("[[Two to Go]]"). After being filled in on everything that has happened to the Scoobies in his absence, Giles apologizes to Buffy, insisting that he never should have left them, but Buffy assures him that he did the right thing. Knowing that Willow is too strong to defeat, he tricks her into draining him of his white magics, which brings him near death. It also allows Xander to reason with Willow as the good magic brings out her natural love and compassion, eating away at the evil within her.

Giles returns to England with Willow for her rehabilitation. A few months later, he brings [[Potential and new Slayers|Potential Slayers]] to [[Sunnydale]] to protect them from the [[First Evil]] and its [[Bringers of the First Evil|Bringers]]. Giles had removed a few volumes from the headquarters of the [[Watchers' Council]], which is soon afterward destroyed by [[Caleb (Buffy the Vampire Slayer)|Caleb]], an agent of the First. An injured Watcher named Robson witnessed Giles about to be decapitated by a Bringer before blacking out. When the Scoobies hear about this, they worry that Giles may have been killed and the First is merely impersonating him. They are relieved when Anya, Dawn, Xander and Andrew tackle him to the ground, proving he is corporeal and therefore not the First. Giles later loses Buffy's trust somewhat when he takes part in a scheme with [[Robin Wood (Buffy the Vampire Slayer)|Robin Wood]] to kill [[Spike (Buffy the Vampire Slayer)|Spike]] ("[[Lies My Parents Told Me]]"). Buffy tells him, "I think you've taught me everything I need to know." Giles believes that Buffy kept Spike around for personal reasons rather than tactical ones; this is confirmed when she talks to Spike the night before the final battle under the Hellmouth. In the series finale, Giles participates in the battle of the Hellmouth, and survives.

Shortly after ''Buffy'' ended its seven-year televised run, there was talk of a Giles-based spin-off series for the [[BBC]] entitled ''[[Ripper (Buffy the Vampire Slayer spinoff)|Ripper]]''. At Comicon in 2007, Joss Whedon stated that ''Ripper'' was still planned and in the pipeline, but as of 2012, nothing has come of the project.<ref>{{cite web|url=https://www.avclub.com/joss-whedon-on-writing-horror-and-superheroes-for-fanbo-1798230884|title=Joss Whedon on writing horror and superheroes for fanboys and casual viewers alike |website=[[The A.V.

In season 5 of ''Angel'', Angel contacts Giles via phone twice. It is established that, after the events of "[[Chosen (Buffy the Vampire Slayer)|Chosen]]", Giles travels to [[Europe]] with Buffy to train new Slayers. He also takes [[Andrew Wells]] under his wing, training him to be a Watcher. In "[[Damage (Angel)|Damage]]", Andrew claims to be "[[The Six Million Dollar Man|faster, stronger]] and 82% more manly" as a result of Giles' mentoring. Later in "[[A Hole in the World]]", after [[Winifred Burkle|Fred]] dies, Angel phones Giles, desperate to get in contact with Willow, who cannot be located. After Angel confirms that he still works for Wolfram & Hart, Giles coldly hangs up on him. Originally, Giles was to appear in "[[A Hole in the World]]" as the one whom Angel and Spike approached in an attempt to save Fred, because Whedon needed a character who would be instantly believed (by the characters and by the audience) when he said there was no way to save Fred. As it was too expensive for Anthony Stewart Head to fly out to Los Angeles to guest-star, Whedon created Drogyn the Battlebrand, who was mystically compelled to tell the truth.
