With Jo and Brooks trapped with Helen, it’s down to Piper and her hastily assembled, rag tag crew to try to save the day. But can they stop Helen before it’s too late?

Last week, Helen pretty much turned into the Terminator, and Jo and Brooks were stuck with her inside a facility with no means of getting close to her with the Killshot or even hiding from her given that she could become a swarm of nanobots and go anywhere she pleased. Piper had convinced Alex they needed to help, but then what could she possibly do?

Turns out, quite a lot. This is undoubtedly Piper’s episode, as Alexa Swinton once again steps up to the plate and proves that she has a range way beyond her years. It’s a credit to her talent that you can honestly believe in the choices she makes, and the fact that the adults in the room all go along with them.

That’s not to say nobody else gets a chance to shine though. Owain Yeoman as Benny has been an absolute revelation throughout, from the slightly untrustworthy investigative reporter to the revealed ‘bad guy’ to the guy desperately searching for his own redemption. Every single turn has been played to perfection, and he gets exactly the sort of stuff to do here that he deserves.

But don’t think that it’s just the A team crashing around in a facility trying to defeat the bad guy who get all the fun. Back at home base, Ed, Abby and Mia get struggles of their own as the DOJ turn up on the doorstep of the Evans home with a warrant to search the place, and every intention of finding the mysterious package with which Ed was entrusted by Jo. The interplay between everyone here is electric, and provides a nice change of pace in the tension between all the life and death running away from stuff elsewhere.

If it has a fault, it maybe gets a little bit gooey and predictable in one denouement, but for my money it earns it and more importantly it really sticks the postscript while setting up nicely for a second series, should the network decide to renew.

Verdict: A fittingly brilliant end to what’s been a marvellous maiden season. Here’s hoping the network agrees and picks this one up for another go. 9/10
