“If you kill characters, then when you have action sequences, you think the other characters might die, too”. In episode 3, Sarah wrongly attributes her phone’s hacking to Kellerman, remembering he had access to her fingerprint off a water glass she drank from during their meeting. “Meanwhile, Sara struggles with the idea that Michael may be alive”, read the synopsis.

Back in the prison, Abu Ramal remains a cartoon terrorist caricature and Rick Yune’s Ja continues to be frustratingly under-utilised, but in a freaky moment he does get to quote Woody Allen, which is pretty much the least Prison Break thing ever.

Poseidon, we learn from Kellerman, is the pseudonym for an ideologically driven member (or members) of the intelligence community who engage in subterfuge to pursue their own ends overseas, by swaying an election, for instance.

T-Bag is convinced that Kellerman is playing him, but Kellerman explains that Poseidon is a man who doesn’t like how the White House handles foreign policy and chose to take matters in his own hands. The assassins from the previous episodes appear to be waiting there, but that’s all we get.

Now just keep your fingers crossed that, as this season approaches its mid-way point, it can continue bounding forward. “Unless you’re killing people, there are no stakes”. If you’d watched Kellerman go from being a ruthless killer, to one of the moral centers of the show, to seeing the possibility of him having been corrupted again – it’s a relief. There are theories though that the brothers will survive and safely land back in the US but one coffin might welcome them as one of the groups is about to follow Paul Kellerman who is now six feet under the ground. They go to see Ibrahim, who offers Michael a full pardon. Kellerman has died for the cause.

Still, filming what might have been Kellerman’s last hurrah was an emotional experience for Adelstein.

Michael, Lincoln and the others take shelter in a shop. Michael getting Ramal in on his MacGyver antics is mildly amusing but also pure generic fare for the show at this point in its life; it’s never not obvious where it’s all going, so pretty low on tension as a result. “Or would you rather be their insurance?” Michael gets angry and tells him he can stay behind – he is a liability.

It’s a pretty good, dramatic scene even if the writers don’t do a great job of explaining why, exactly, the cells are so easy to break out of if the two prisoners can just find a way to overcome their differences and work together. Now they have to figure out how to get out of the city and how to get out of the country without the airport and that takes them across the world, essentially.

Eventually the group gets out but is soon confronted by ISIS soldiers and everyone predictably betrays one another.

Naturally, the drama inside the prison is more intriguing, as Michael’s staging an escape plan is juxtaposed opposite Cross’ attempt to reach Ramal. “On some level, once you start finding things out, once somebody gets too close to the truth, they either have to reveal that truth, or they have to die”, executive producer Paul Scheuring says. “We’re not going to starve the fans until [the finale], I promise you that”.
