They both got lost as night fell and were attacked by a werewolf–later revealed to be a man named Lee Tully, who later comes looking for him in search of companionship–who killed the tourist and scratched George, who survived when the rescue services found him.
He works alongside Mitchell as a porter in the local hospital, unable to hold down a more permanent job due to his monthly transformations, which are extremely painful.
Alex is captured and subsequently killed, fatally drained of blood as part of the vampire Cutler's plot to both seduce and punish Hal.
[12] Rook and the Men in Grey play a more prominent role in Series 5, when they fall victim to government budget cuts which will close the department within three months.
Distraught by the news, Rook is driven to increasingly desperate measures and moral compromise in order to save the Men in Grey and his own life's work.
[18] Herrick returned in the fifth episode of Series Three, apparently traumatised by what he experienced while dead, as he is seen in a hospital in a straitjacket, showing terror when Mitchell attacks him and confused when he realises that he cannot see his reflection in a mirror.
Despite his apparent personality changes, such as his attempt to console George over his fears about becoming a father, his expressed disdain for Annie's goodness, coupled with him directing Nina to a scrapbook of Mitchell's past murders, suggests that some part of him remains underneath his amnesia.
The ghost in question (initially credited as "The Woman") was the ruthless former leader of a London-based human resistance movement during the time of vampire dominion over the world.
In the future, with the resistance gradually losing the battle, she had consulted stolen vampire lore and found out deeply troubling information about Eve's role as War Child.
She attempted several methods including autosuggestion via radio and television (in the manner of Purgatory's Gatekeepers, as seen in Series 2) and sending another ghost (Kirby) back to the living world as an assassin.
Annie eventually caused Eve's death in the final episode of Series 4 (The War Child) when her only remaining option was to trigger an explosion which destroyed the Old Ones and ended their plans for world conquest.
The lesson must have worked as in the present Cutler has no problem manipulating or killing humans although he still feels guilt, confusion and anger at Hal for making him 'abandon his entire species'.
During the whole of Series 4, Cutler devised and put into action a vampire-protecting plot, intending to set up an anti-werewolf panic amongst humans which would encourage the latter to seek vampire assistance.
He went on to stage a "grand reveal" in which a wolf-form Tom would be tricked into massacring humans on camera, resulting in footage which would go viral and incite an anti-werewolf movement.
Allison hunts Golda, but Tom dissuades her from killing: he persuades her that her parents still love her, and that there are ways of staying human even if she turns into a werewolf once a month.
Crumb's confused, destructive and predatory tendencies are currently being manipulated by Dominic Rook, who is using them to demonstrate to Alistair Frith that the Men in Grey are still needed to protect against supernatural threat.
While Crumb's human emotions are being rapidly eroded by his growing vampire nature, he refers to this in particular as "a sore point" and has exhibited flashes of remorse, horror and grief over his actions.
Towards the end of his debut episode, it's revealed that he is behind the spate of suicides at the hotel when he whispers "a little secret" into the ear of the maid Sophie, who's subsequently driven to kill herself (and, before she does so, to write "He Is Risen" in letters of blood on the wall).
When Hal and Tom take jobs at the hotel where he is currently staying, Hatch sees a prime opportunity to gain plenty of energy from a vampire/werewolf conflict and devotes himself to promoting discord between them.
Both Oliver and Albert (who was only pursuing his brother in order to try to comfort him) passed on into the afterlife and closed their ghost door behind them, marooning the squad of Gatekeepers in the world of the living (where, cut off from their life force, they soon dissipated).
Mary is delighted to have a new friend who she feels can understand and share her present-day interests (which include sexual voyeurism, mental eavesdropping and malicious manipulation of living people).
Alex is alarmed at Mary's unbalanced lack of restraint and perspective, believing that a similar fate might await her if she remains an earthbound ghost for too long.
Bitter and resentful, Larry refuses to take any personal responsibility for what has happened: instead he claims that his lycanthropy denied him any choices ("the wolf took it all") and that Tom's attempts to better himself will always result in similar failure.
Heartbroken and despairing, Tom temporarily leaves Honolulu Heights to live rough, until he is persuaded to return by Hal and Alex, who emphasise their faith in his ability to cope with his condition.
Unwilling to depart from Honolulu Heights to return to living rough (and, perhaps, nursing a deathwish) Larry instead goads Hal into assuming full vampire state and attacking him.
