There's at least two invisible pawns in the room. Each picture I'm looking at whomever I ran into.
Pawn 24 is still in the med bay.
It feels to me like there should be more dialog after Pawn 4 left but there isn't. I also can't engage in conversation with anyone. Only Pawn 32 had any dialog options and with her, there was only two. Everything else was on rails (again, not sure if that's normal or not).
