John Mitchell (Being Human)

This is a list of fictional characters in the British supernatural drama-comedy television series Being Human. The show's central premise follows a vampire, a werewolf and a ghost as they try to live together in modern-day Britain. Actors Lenora Crichlow, Russell Tovey and Aidan Turner composed the original core cast of the programme's first three series with Sinead Keenan joining the main cast in series 3. This setup began to change from series 4, and by the fifth series an entirely different werewolf, vampire and ghost trio played by Michael Socha, Damien Molony and Kate Bracken were starring.

Anna Clare Sawyer (Lenora Crichlow), known commonly as "Annie", is a ghost, appearing as she did at the time of her death in her early twenties. Up until her death, she had been living with her fiancé Owen (whom she later revealed had been her third serious relationship, her previous two having ended when her first boyfriend posted naked pictures of her on the Internet and when her second boyfriend drunkenly invited her mother to form a threesome). Following her death, she haunted the house in which she and Owen had lived while she was alive, and which Owen was now running as landlord (eventually renting it out to George and Mitchell). Annie's ability to be seen and heard by normal people depends on her state of mind, although supernatural creatures can always see her. Annie eventually falls in love with Mitchell and is devastated when he volunteers to be staked by George. When George and Nina are both killed in a war against the vampires, Annie takes responsibility for their daughter Eve, along with new housemates Tom McNair and Hal. In the Series 4 finale she sacrifices herself and baby Eve to destroy the Old Ones with a bomb Tom made. With her unfinished business taken care of, her Door to the other side appears once more, and she passes through it to reunite with her friends.
