Might've missed a detail or something in the dialogue:
OK, so they're only waking up "Troy" when needed for some crisis, makes sense why he looks the same age. The senator is working on "shifts", so she's still alive but clearly looks older. What was Viktor doing? If he's working shifts like the senator, he didn't look a day older. He said he liked working with Keene/Troy, but he's been awake prior to Troy waking up every time, and seems to be much more aware of things as if he's working shifts. Is there some longevity tech he's using that the senator isn't? Are they just handwaving it and I'm looking for an explanation to something that isn't there?
He was working shifts, though he seemingly had more control over his as the old founder that was from “security” indicated he tried to line up with Troy. However, that makes no sense as Troy is only awaken in emergencies. They aged him slightly each time we saw him.
What I’m curious to learn is how much each of the founders is brainwashed. Troy and his sister clearly were. They left it ambiguous with respect to Victor and the older guy that was “security”. The director obviously still had her memories.
I bet they will make Juliette a descendent of Troy. I was also surprised Silo 1 used gas to kill, I just assumed it was nano machines after all the time they spent on them this season.
