Liz and the gang hatch a plot to try to contain Jones and free Maria. Alex starts to learn some harsh truths about the Lockhart machine from Eduardo.

So, a malevolent alien is piggybacking someone else’s body and holding an innocent woman prisoner in her own mind – sound familiar? Didn’t we do all this before in Roswell New Mexico with Noah? Certainly the parallels are not lost on Isobel, who is struggling with the familiarity of what’s going on and what this means for her beloved brother.

But Liz Ortecho is seldom a woman without a plan. Having determined that her beau isn’t exactly himself at the moment, she thins she has a way to lull Jones into a false sense of security so that they can overpower him. Key to that plan will be locating his sword and making sure that he can’t get hold of it. Easier said than done.

Alex is starting to learn an awful lot more about Eduardo, beyond the fact that he’s Kyle’s uncle. This is a man who – quite contrary to being the same sort of monster Alex’s father was – seems to be a genuinely decent man using the Deep Sky project to get answers. And it rapidly becomes clear that he knows a lot more not just about Alex but about the various specific goings on and inhabitants of the town. Can he really be an ally? For Alex, this is a tougher question than it might be for most people, remembering how much his own father betrayed him on more than one occasion. Trust doesn’t come easy to Alex Manes.

Rosa is meanwhile still struggling with her newfound powers but wants to help in the plan to take down Jones. Approaching Michael, with whom she has been starting to get closer of late, randomly reveals a way in which she may well be very useful indeed. When she’s not fine tuning her new abilities, Rosa meets a new priest who offers her some fresh perspectives on her struggles to keep clean and on the right side of her old habits. It’s nice that not only have the writers not forgotten Rosa’s struggles with addiction, but that they are organically and usefully integrating it all into her character’s arc here. Rosa needs to feel useful not just for the sake of it, but because the high of helping those she loves may just be enough to replace the high she used to find in a bottle of pills.

As things race towards their conclusion, there’s a slight sense of inevitability to exactly how things play out, but it’s entertaining nonetheless, as well as providing just one more massive revelation which flips everything our heroes and the viewers understand about Jones and exactly what is going on. Things promise to be explosive from here on.

Verdict: Genuinely tense, with another round of standout performances and surprises aplenty. 9/10
