Last week we left off with the trinity is a state of disarray – Hal on a murder spree, Tom whittling his stakes and Alex transported to her own grave with a decomposing corpse for company. It doesn’t take long for all of this to be resolved, since we’ve got plenty to get through, but a jaunty song and dance number from Hal gives us one last glimpse of the altered character before the three of them get back to business. It also reminds us of Being Human’s unique ability to combine the ridiculous with the horrific, as well as the mundane with the supernatural.

It’s smart of the episode to go over these overarching themes in the final episode, since what happens next requires the audience to understand the struggles the three of them have always been dealing with. There are no easy moral triumphs or moments of heroism to be found here, because Being Human was never about that – it was about a monster’s quiet search for mundane, human existence. With this in mind, seeing Hal selfishly use another vampire’s blood to use in the ritual isn’t such a weakness. He wants to survive the ordeal because he wants to live, just like he did a century ago. It might not be cosy or comforting, but it feels honest.

Tracking Hatch down to the site of his master plan, the three of them are transported to tempting alternative realities in which they were never afflicted by their respective supernatural curse. This is where the episode gets really, really brilliant. Starting with Hal, he is taken back to the moment he became a vampire, bleeding out in a battlefield and ready to die. Then there’s Alex, who finds herself back on holiday with her family, getting ready to meet Hal for their ill-fated date. Tom, on the other hand, is offered a more overt ‘alternative’, as a pregnant Allison embodies the normal family life he believes he can never have with the wolf inside.

But they know it’s a lie almost immediately and, though tempted, ultimately turn the offer of a new life down in favour of fighting together for humanity’s freedom. The episode spends an inordinate amount of time in each dream-world, and this allows us to really see the worth of the show as a whole. Deep down, they’re human, and we get to see the best of all three characters as individuals, as well as celebrating what’s gone before. A lot is said here that will prove important to deciphering the episode’s end (read our theory on that, here), but this section of the episode can also just be enjoyed for its simple summarisation.

The gang awakes back in the TV studio just in time to witness Rook shoot Hatch, and the devil vacate his vessel. Returning home, Rook comes around to announce his retirement. But, with some clever attention to detail from Hal, we learn that the devil has actually occupied Rook’s body, and the three of them finally finish him off properly. Instead of dying, as they believed they would, they discover that the devil’s demise has actually made them human. Cue ice cream, telly and domestic bliss. Well, that’s what you can believe if you want, but the final shot throws everything up into the air with a slight turn of a camera angle, and it’s clear that things aren’t quite that simple.
