[spoiler] um...Could we not just have come back for him?

[Romulator]

Its not sure that he cant get out. Maybe he finds another tool? Or the door auto unlocked?
And there is plensy woman in omicron... theyre a little bit bitchy and winey but well he should get along XD

In reality, Simon-2 is stuck. There's no tools for him to use since we took the only Omni-Tool, Catherine locked the door to the Screamer, and Simon-2 cannot sustain the pressure of the Abyss (or perhaps even call the elevator).

He is, essentially, screwed.
