List of Being Human (British TV series) episodes

For episodes of the Canadian/US adaptation, see List of Being Human (North American TV series) episodes.

This is a complete list of episodes for the BBC Three television series Being Human. Being Human is a supernatural drama-comedy television series which is broadcast by BBC Three. The original premise of the series was that a ghost, a vampire, and a werewolf became friends and began living together in a house in Bristol. All three characters appear to be in their 20s. The programme's original cast included Lenora Crichlow as Annie the ghost, Russell Tovey as George the werewolf, and Aidan Turner as Mitchell the vampire.

Beginning in Series 2, Sinead Keenan was promoted from a supporting to a main character as George's werewolf girlfriend, Nina. At the start of Series 3, the characters moved to a new house in Barry, Vale of Glamorgan. Turner left the show at the end of Series 3, and his character was killed off. On 11 November 2011, Russell Tovey announced that he was leaving Being Human after Series 4 to work full-time on his other show, Him & Her.

A pilot and 29 episodes have aired. Series 4 premiered on February 5, 2012.

Originally, the pilot episode and all episodes of Series 1 and 2 were untitled. Semi-official names have since been provided via a competition run by series creator Toby Whithouse via his blog.

Pilot (2008)

1	1	"The Monsters Within"	Toby Whithouse	Declan O'Dwyer	18 February 2008 (2008-02-18)	430,000
Two Bristol-based young men, George (a werewolf) and Mitchell (a vampire), have formed a friendship and desire to live in as normal and human a way as possible. They move into a houseshare together only to discover that their new home is haunted by Annie, the ghost of a previous occupant. As the three endeavour to deal with each other and develop their friendships, George must deal with the unexpected return of the girlfriend whom he abandoned once he became a werewolf (and who does not know the truth of his condition), while Mitchell must deal with the imperial ambitions of the Bristol vampire clan and his recent creation of a new vampire, Lauren.

Series 1 (2009)

The series dealt with a supernatural threat, Herrick, a Vampire Leader. The cast and tone of Being Human changed between the pilot and the series. Compared to the pilot, producer Matthew Bouch described the series as "less gothic and slightly more rooted" as well as "a bit funnier"; he also described the series as "kind of a reboot" of the pilot. Writer Toby Whithouse, however, said that he does consider the pilot to be canonical.

Interior shots of Mitchell, Annie, and George's home, the hospital, and the vampires' funeral home headquarters were filmed on sound stages with exterior shots filmed on location. The funeral parlour's exterior and reception room were filmed in an old car showroom in Bristol, while the back rooms were filmed in a television studio.

To promote the show, the BBC launched a blog, and on 22 December 2008, the BBC Being Human web page aired three prequel videos to introduce the three main characters: Mitchell's is set in the 1960s, George's is a video diary of his visit of Scotland, and Annie's shows her as a ghost terrorizing a couple who had moved into the house. Series one of Being Human premiered in the US on 25 July 2009 on BBC America and on 4 August on Fox in Portugal.

Metacritic assigned a rating of 79 out of 100 based on 8 critical reviews, with reviews averaging 7.8 out of 10.

George saves him, but after they have recovered from a night as werewolves, he tells Tully he never wants to see him again.

In a review for the episode, IGN gave it a 7.9 out of 10, saying that "[c]reator Toby Whithouse has done a brilliant job of developing these characters and their stories in such a short period of time without dumping a ton of exposition on us or allowing the narrative to get too convoluted".

Herrick plans to kill George and Nina, and destroy the things keeping Annie Earth-bound, sending her into "nothingness". Mitchell will then have to face the vampire coven alone and be destroyed. Can George keep Nina safe? Can Annie harness her new poltergeist powers in time to defeat the vampires? Will Mitchell succeed in his plan to face Herrick once and for all? In the end, nothing goes as planned for any of them. IGN gave the episode 8.5 out of 10, with the reviewer saying "[he's] dying to see the universe they reside in expand a little now that they've killed off the local threat" and he was eagerly awaiting more Being Human.

It was expanded to eight episodes, with series creator Toby Whithouse writing the first two and last two episodes.

A prequel posted on the BBC website introduced two new vampire characters: Ivan and Daisy. BBC America began transmitting Series 2 on 24 July 2010.

This series was concerned with a human threat, CenSAA.

With the help of Nina and George, who have taken jobs at a nearby hospital, Mitchell crosses over to "the other side" after a patient dies. He encounters Lia, a young woman who helps guide him through purgatory. But when Mitchell begins encountering disturbing, guilt-inducing situations from his own past, he realizes Lia's motives in helping him may not be pure. Meanwhile, George encounters Tom McNair (Michael Socha), a young man in the woods making the area safe for his werewolf transformation. Tom flees, George gets arrested by the police, and Nina must rescue him before they both begin their monthly transformation. Meanwhile, the audience learns that local vampires have imprisoned Thomas' father (Robson Green) and have put him in a cage match with an ordinary human for fun.

The episode's cold open depicts a teenage vampire, Adam (Craig Roberts), being fed blood by his own (human) parents during the 1970s. In the present, Adam (still physically and emotionally a teenager, although now 46 years old) and his ailing, elderly father are admitted to Nina's hospital. Realizing the teenager poses a threat to the community, they track him down and bring him home for Mitchell to deal with. Mitchell, meanwhile, is contacted by Richard Hargreaves (Mark Lewis Jones), a representative of the "Old Ones" (ancient vampires living in peace in South America). With the police looking for Mitchell after the Box Tunnel murders, Hargreaves offers to get Mitchell out of the country. Hargreaves and his wife (Melanie Walters) offer to take Adam in, and Mitchell agrees. George and Nina aren't so sure that the Hargreaves are offering the wholesome home environment Adam needs, and they investigate—leading to a confrontation with the Hargreaves and their secret, kinky lifestyle. The episode concludes with someone inside the hospital's locked mortuary attempting to get out.

Sasha follows Annie home, where George, Nina, and Mitchell are stunned to realize Sasha is a zombie (a "Type 4" in the nomenclature of Kemp's organization from Series 2). Sasha refuses to believe she's dead, and Annie tries to help her confront the truth. Meanwhile, Mitchell discovers Sasha isn't the only zombie, and that hospital personnel have performed horrific experiments on the others. (This ties in with the final moments of the previous episode.) Mitchell also discovers he has a groupie, Graham (Tony Maudsley)—an overweight, nerdy, middle-aged vampire. Graham's obsession with Mitchell quickly grows out of hand, and he not only insinuates himself into Mitchell's life but says he will tell George, Nina, and Annie about Mitchell's complicity in the Box Tunnel murders if Mitchell tries to stop him. As George and Nina discover that Nina might be pregnant (which comes with its own revelation about Nina's past), Mitchell must confront Graham before Graham reveals Mitchell's secret or does something even worse.

Annie and Mitchell struggle with how to consummate the physical side of their new love affair, which leads to a threesome with a drunk woman that almost goes terribly wrong. They realise their relationship must remain spiritual. Worried about Nina's pregnancy, Nina and George seek out McNair (Robson Green) for advice. His son, Tom (Michael Socha), becomes infatuated with Nina, and the McNairs enter the Honolulu Heights B&B at night. They're caught by Mitchell, and Tom is injured. Nina convinces McNair that Tom must have medical care, and McNair agrees to stay in the house for 48 hours. McNair says Tom was born a werewolf and that vampires killed his wife. But Nina suspects McNair is lying to his son, and soon Tom learns the truth about who he is. Discovering that the McNairs are vampire-hunters (and McNair might be the "werewolf-shaped bullet"), Mitchell turns McNair over to Richard Hargreaves (Mark Lewis Jones) for imprisonment in a cage-fighting scheme (the "dog fights" last seen in Episode 1 of Series 3). But Hargreaves kidnaps George, Nina, and Tom instead in vengeance for George and Nina's previous actions, and Mitchell and McNair must try to save them. In the episode's final moments, William Herrick (who was resurrected in the final moments of Series 2, Episode 8) reappears.

George discovers resurrected vampire William Herrick (Jason Watkins) as a confused and gentle amnesiac in his hospital's psychiatric ward Herrick had been resurrected by two other vampires, Cara (Rebecca Cooper) and Daisy (Amy Manson), at the very end of Series 2, with the consequences not seen until now. To prevent Herrick from being discovered, George and Nina kidnap him from the hospital and take him to their home. Mitchell tries to kill him (with George's eventual agreement) but Nina stops him. She becomes disturbed that George has agreed that Herrick must die. Meanwhile, it is unclear as to precisely how much of his previous life Herrick remembers, which raises the question of whether he can still be condemned as evil. The house is visited by a frazzled social worker (Nicola Walker) with an addiction to energy drinks and a nicotine inhaler. Cara arrives on the trail of Herrick, asking Mitchell's help in finding him: Mitchell agrees, but demands that Cara tell him the secret to vampiric resurrection so that he won't die from the "werewolf-shaped bullet." However, Herrick cruelly rejects Cara, who commits suicide. As the stress of his impending death wears on Mitchell, his relationship with Annie deteriorates drastically. While George and Nina believe Herrick is no longer evil, Annie disagrees, having had a confrontation with him in which his crueller side appears to show. Both George and Nina have difficult confrontations with Mitchell, and Mitchell and Annie reconcile. Herrick discovers a horrible secret. While his precise state of mind is still unclear, he is clearly still manipulative enough to persuade Nina to cover that secret up - at least from her friends.
21	6	"Daddy Ghoul"	Lisa McGee	Philip John	27 February 2011 (2011-02-27)	985,000
The episode's cold open depicts a scene from 1933 in which Herrick and Mitchell discuss what it means to be a protegé. George learns his father has died, surreptitiously returns for the funeral, and reconciles with his father (guest star James Fleet)—who, it turns out, isn't dead. He moved out when George's mother began an affair with another man, and faked his death. George visits his mother, and is bullied by her lover. He later tries to reconcile his parents. DC Nancy Reid (Erin Richards) begins investigating Mitchell for the Box Tunnel murders. Mitchell tries feeding his own blood to Herrick, but this fails to awaken his vampirism. But he later feeds off a bloody tissue left behind by Reid. Annie learns that Lia (the ghost from Series 3, Episode 1) was one of the Box Tunnel victims, but Mitchell denies knowing her. Annie starts to help Reid solve the murders, but unwittingly leads her to suspect Mitchell.

In the cold open, the audience learns that Herrick kidnapped McNair 20 years earlier and put him against a werewolf in werewolf-human cage match. McNair won, but became a werewolf. In the present day, DC Nancy Reid's suspicions about Mitchell's involvement in the Box Tunnel murders grow. An injured McNair and his son return to Honolulu Heights. Herrick struggles with his inner demons and emerging vampirism. Mitchell is increasingly desperate to learn the secret of resurrection, Annie learns the truth about the Box Tunnel massacre, and DC Cooper (Justin Salinger) reveals his own secret to DC Reid. Both McNair and Reid set a trap for Mitchell, but in the end Herrick has the upper hand. McNair is killed when he attempts to kill Herrick, whose memories are restored after he drinks from DC Reid. Meanwhile, Mitchell is arrested and police attempt to take his photograph. Fully returned to his old self and bent on vengeance, Herrick steals a police uniform in order to infiltrate and take advantage. Before leaving the house, he attacks and stabs Nina, leaving her for dead.
23	8	"The Wolf-Shaped Bullet"	Toby Whithouse	Daniel O'Hara	13 March 2011 (2011-03-13)	1.1 million (overnight figures)
Tom discovers the injured Nina with the corpses of Reid and the massacred policemen at the Honolulu Heights House. Receiving a message from Lia, Annie returns to "the other side" and learns that the "wolf-shaped bullet" prophecy was a ruse intended merely as a self-fulfilling prophecy. Mitchell is rescued by Herrick, who massacres more policemen. Herrick puts Mitchell in a cage with George, who blames Mitchell when Herrick claims to have killed Nina. An angry Tom (ignoring McNair's written plea not to seek revenge) interferes with Herrick's plan and Mitchell and George are freed. George and Tom learn Nina has survived. Annie convinces Lia to stop seeking revenge. Mitchell tries to reason with Herrick, but then kills him with a stake when Herrick proves too power-hungry. One of the "old ones," Edgar Wyndam (Lee Ingleby), frames a man named Jason Healey for the Box Tunnel murders. Annie reads about his arrest in a tabloid. Mitchell, believing it is inevitable that he will kill again, urges George to kill him. George is initially very reluctant, but is preparing to kill his friend when Wyndam intervenes, promising a vampire uprising. To save Mitchell from being a pawn in Wyndam's plans, George kills Mitchell.

Series 4 (2012)

On 13 March 2011, Whithouse and BBC Three announced that Being Human would return for a fourth series. Eight 60-minute episodes were commissioned.

The producer also said some old characters would return, and he intended to introduce new ones. Radio Times reported that the fourth series is likely to air in early 2012, and that the characters will continue to live on Barry Island. On April 19, 2011, BBC America announced it would co-produce the fourth series with BBC Three.

On 30 April 2011, actor Michael Socha, who plays the innocent young werewolf Tom, told the Derby Telegraph that he'd been asked by Toby Whithouse to appear in Series Four. On 26 May, actor Craig Roberts told British magazine SFX that his character will return to the show. Roberts, who plays the eternally teenaged vampire Adam, said, "I believe I am going back for an episode. They've not mentioned too much about Becoming Human. If that does get mentioned again I'm all for doing it because I thought it was a great thing. I'm really happy to do Being Human again because it's a fantastic show, and if Becoming Human wants to go again, I'm game." On July 22, the Warrington Guardian reported that 22-year-old Andrew Gower had been cast as Cutler, a vampire who will become one of the main characters on the show. South Wales actor Darren Evans will also appear on the show, although the nature of his character was not stated.

On October 16, 2011, SFX magazine revealed that Irish actor and 2011 Spotlight Prize nominee Damien Molony (a recent graduate of the Drama Centre London) had been cast as the new vampire Hal. Molony told the magazine in an interview that Hal is an upper-class, very English, well-dressed vampire for which the writers have laid out an extensive back-story. Molony also revealed that his character will fall in love. Series creator Toby Whithouse told the online version of magazine Digital Spy that the series would "have to re-establish...relatively soon in series four" the main concept of a vampire, werewolf, and ghost living in a home together, but declined to comment further on what the details of this might be. In an interview with the Web site CultBox, series star Russell Tovey said that Hal would be "the new head vampire."

Series star Russell Tovey denied rumors that his werewolf character George Sands might not appear in the entire series. In his CultBox interview, Tovey said that the plot lines were "very spread out", that "a lot more happens", and that a number of new main and recurring characters had been added to Series Four. "[T]he storyline is going completely crazy,..." he said. Dave Golder, writing for SFX magazine, concluded that Tovey's comments meant fans would see less of George and more of the new characters, and that Whithouse would be likely to reinvent the show with all these changes.

The filmmakers returned to Barry Island to film season four in late July 2011, where they continued to use local man Gary Rowe's house as the group's bed-and-breakfast base of operations. Students from the drama and theatre programme at Coleg Gwent were used as extras and in minor roles on the show. Cast member Damien Molony said in mid-October 2011 that several scenes for the series' final episodes had already been filmed.

On 11 November 2011, Russell Tovey announced he was leaving the show after Series 4.

The March 2012 issue of SFX magazine revealed the episode titles for series four as part of a preview feature.

By evening time, Hal has changed his mind about his loyalties and when the vampires attack the cafe, Hal helps Tom escape back to Honolulu Heights (bringing along Michaela, who has become caught up in the action and is delighted to find her fantasies are real). At Honolulu Heights, they find Annie and Regus preparing to leave: as the vampires attack, Hal pretends to side with Fergus but then betrays and stakes him. Fergus' remaining vampire sidekicks are killed in the following melee, and Michaela is fatally wounded. Regus makes her into a vampire (in part, so that he can have a companion and lover of his own) and the two leave together. Reassured by Hal's display of loyalty and his growing friendship with Tom, Annie decides to stay in Barry. x

Kirby, a ghost from the 1970s, arrives at Honolulu Heights. He claims to have been a former nursery school teacher, sent from the afterlife by Nina in order to help them all look after Eve. Apparently friendly and eager to please, he immediately begins sowing dissension in the group, manipulating them into distrusting each other and insinuating himself into Annie's affection. When a doctor is called to check up on Eve and becomes suspicious, Kirby follows him to his car and kills him by stopping his heart. Kirby's machinations succeed in breaking up the household, with an enraged Tom leaving of his own accord, and Hal (framed as a threat to Eve) subsequently ordered to leave by Annie. Now left as Annie's only support, Kirby brutally mocks and taunts her, revealing both his hidden contempt for her and his true identity: a serial killer who wormed his way into families and eventually murdered them. This, on top of the breakup of her household, causes Annie to dissipate, and it's then revealed that Kirby has in fact been sent by "The Woman" in order to kill Eve. Discovering Kirby's treachery, Tom and Hal return to the house to stop him, resulting in a Mexican standoff. This is broken by the return of a vengeful Annie (re-empowered by the restoration of the household) who kills and dissipates Kirby. The reunited Honolulu Heights "family" celebrates Tom's birthday. However, when alone, Hal reveals that he has a burn on his arm, suggesting that he is Eve's "Nemesis" as revealed to Annie by Regus in the previous episode.

Cutler is killing people and staging fake werewolf attacks, planning a staged expose in order to distract the public from finding out about vampires. Meanwhile, Permanent 'teenage' vampire Adam (having apparently become separated from his friends as seen in the Becoming Human spinoff) becomes romantically and sexually involved with Yvonne Bradshaw, a middle-aged schoolmistress. Fleeing the press, they come to Honolulu Heights in order to hide out. While there, Adam is photographed by the journalist Peter, who realises Adam's vampire nature when his image does not show up on camera. Already investigating the hidden world of vampires for personal reasons, Peter enlists the help of Cutler. After both Tom and Hal fall for Yvonne after she has touched them, Hal realises that she is a succubus - a half-supernatural seductress who first bewitches men and then drains life from them via sex. Annie manages to separate Adam from Yvonne and tries to help both of them come to terms with her condition. Despite a period of self-disgust and resentment during which she almost kills Tom, Yvonne eventually accepts her nature, aided by Adam (who despite his initial disgust comes to realise that he genuinely loves her) and the two leave together. Aware of Cutler's true nature, Peter attempts to trap and expose him but his plan backfires and Cutler kills him. Cutler uploads filmed werewolf transformation footage to the Internet and begins his expose.

Tensions run high when Cutler takes Tom under his wing. Annie travels into purgatory and meets Eve, who shows her the future-- most of the human race is dead-- and tells her that she (Eve) is actually the Nemesis. Hal meets Cutler again (it was Hal who turned Cutler back in 1950), and he tries to get Hal back to his old days and ways of drinking blood. Hal hesitates but Cutler does his best and Hal breaks down. Hal is then seen drinking a glass of blood before meeting up with Alex on a date; however they get in a fight and Alex leaves but one of Cutler's men follows her. To fulfill the prophecy Eve asks Annie to kill her when she is a baby. Later we find out that Hal killed Cutler's wife and made him drink her blood and Cutler does the same to Hal by revealing Alex's dead body. Cutler locks Hal up but Alex returns as a ghost and helps Hal escape. Cutler carries out his plan-- as the building fills with young people arriving for a dance, Cutler locks Tom in a closet, and after Tom changes he is released onto the dance floor. However, Hal warns everyone to escape, and although Cutler had locked the doors, Alex opens them. Everyone escapes, Alex then shuts the doors, and Hal confronts the werewolf alone. Later the Old Ones arrive and they are thirsty for blood.
