“Superposition”
Jason 2 is becoming more manipulative with every second. He accidentally gives his son ice cream with nuts in it, not aware that the boy has an allergy to them. This started some questioning by Daniela about what was going on.
Then, man the Box is a perfect way to get rid of bodies. Imagine, you could just drop a body off in some nearby dimension and no one would ever know. Jason 2 does that very thing, albeit not a dead body, when he tricked Ryan into going with him into the Box only to strand him in an alternate universe.
Jason and Amanda are starting to feel the stress of their continued failures at finding Jason’s actual universe. They’re coming across so many that are just a little different and they were feeling it. They are also growing closer to one another, bringing even more stress into the situation.
Jason 2 sealed up the Box at the end of the episode, seemingly finishing his plan. However, I get the implication that Jason 2 may not be as happy in this universe than he thought he would be.
I am not sure what will happen next, but I do think the doubts that have creeped into Daniela’s mind will continue to grow as Jason 2 increases his efforts.
