There’s a little more exploration this week of what possibilities the bridge between the two universes hold: Earth-2 has a serial killer, so why not pop over with his counterpart from our universe, who is a non-murdering forensic psychologist, to help find the guy? They do their best to prevent him from finding out that he’s investigating his counterpart in the other universe (or even that there is another universe), but of course that’s going to come out. And when it does, John McClellan goes rogue to try to save the serial killer version of himself. Instead winds up the victim of the killer’s memory-extracting machine (swear to God), which the killer uses to try to make himself feel better. The psychologist is able to pinpoint the event that made him a doctor over here and Dexter over there, so at least the murderer to get a little bit of peace, before blowing his own head off.
Anyway, we also get to see what the Peterlessness means for the other universe, and the best aspect is that AlternaBroyles is still alive. And you’ll be glad to know that even though this week’s plot seems to organically serve as commentary on the “where’d Peter go?” storyline, the dialogue is still as subtle as a sledgehammer to the temple, with Astrid wondering if Olivia has ever considered the fact that maybe her type just “doesn’t exist.” He exists, all right, and Walter can hear him, but the poor man thinks he’s going crazy.
