Annie Sawyer Season 3

Trailing series 3, Annie appeared in a series of videos on the BBC website, sending messages from the other side. In the final one, viewers saw that she was being sent to hell, with the gatekeepers making a special room for her and burning the key. However, she is subsequently permitted to leave with Mitchell when he enters Purgatory to recover her. Lia – Mitchell's spiritual guide- informs her that the complications were caused by her entering the afterlife through the 'wrong door', although noting that she will still have to come back through the right one eventually. Upon returning from Purgatory, Annie is reunited with George and Nina in the quartet's new home in Barry Island, Wales.

Overwhelmed with gratitude to Mitchell for having rescuing her, Annie begins to fall for him and appoints herself as his guardian angel. Although her first attempts at helping him end in disaster, she manages to get him a job. On a celebratory walk on the seafront, Mitchell tells her she must stop defining herself by what she does for other people, but Annie opposes this, expressing that it was he, George and Nina that she came back for and that if it wasn't for them she might as well be in Purgatory. After learning that Mitchell's journey into Purgatory to rescue her had resulted in the creation of at least five zombie-like beings – dead bodies who nevertheless continued walking and talking – Annie attempted to help Sasha, the last surviving 'zombie', adapt to her current state. She providing Sasha with a makeover to conceal the worst of her decay, and when this failed, remained with Sasha as her body finally collapses. After this, Mitchell's resistance to Annie's love weakens, and he attempts to tell her the truth about his recent actions (including the Box Tunnel Massacre). Annie stops him before he can confess, assuring him that – regardless of the terrible things he'd done in his past – all she cares about was the man he was now. The two subsequently kiss and embark on a full partnership.

However, attempts by Annie and Mitchell to develop a sex life are unsuccessful. Annie attempts to bypass the problem by suggesting that Mitchell has a one-night-stand while Annie 'shares' the experience with the woman. This plan backfires when Mitchell's vampire instincts take over and he attempts to drain the woman's blood, although he stops himself. After sending the woman away, he admits to Annie that he's actually content to have a non-physical relationship with her (as sex has always been about violence with him rather than love) and that he regards their relationship as something 'pure'. Things took a turn for the worse when Annie finally learned that Mitchell had been involved in the Box Tunnel 20 Massacre. Devastated, she convinced Mitchell to let himself be arrested despite the wider dangers if his true nature is discovered.

In the third series final, Annie learns of Mitchell's "wolf-shaped bullet" and that it was the price of her return. After discovering Nina injured in the hospital and receiving a message from the other side, she returns to purgatory in the hopes of sacrificing herself to repel the prophecy, but learns from Lia that there was never any prophecy at all. Lia intends to keep Annie in purgatory in order to deprive Mitchell of her – Lia's true revenge on Mitchell. Annie also witnesses the fight Herrick had stirred up between George and Mitchell, and Lia informs her that Mitchell had fulfilled the nonexistent prophecy himself. Annie concludes that Nina must still be alive as she has not passed over, and convinces Lia that her revenge is unjust. Lia allows Annie to depart, and Annie arrives back in the hospital to find Nina alive and still carrying the baby.

Back at the house, Annie, George and Nina find a blood-soaked Mitchell on their doorstep. Mitchell persuades George to kill him and bids farewell to Annie with the words "You were the love of my long life". She replies that he is the love of hers, but before George can stake Mitchell, Wyndall appears and announces that the vampires are taking control of the world. He implies that Annie is a lot stronger than she imagines. But when he says that Mitchell will be used to kill for him, George stakes Mitchell in the heart. Annie, George and Nina watch as their vampire friend disintegrates, then stand together as they warn Wyndall that he has a fight on his hands.
