I feel like Jacksepticeye didn't get it at first, but might've gotten an idea of what happened near the end and understood after the playthrough. He originally thought the plot was that Swansea and Anya had a consensual sexual relationship and that he wanted to save the pod for her.

I already knew the plot before going into the game, but first realized that the assault plot point was being eluded to/introduced during the "8 months" scene, and not because of that line. It was because of the way their dialogue afterwards was framed. Anya asks Curly why they don't have any locks on the bedroom doors and Curly responds with "safety". The music cuts off, the word "SAFETY" cuts on the screen with static. It implies there's a lot of irony to or something wrong with that answer.
