> for the assassination attempts I escaped, I don't recall there being any indication of who sent them or any option to remove someone after.
If you ESCAPED rather than SURVIVED, in the sense that you got away and never proved that an assassination attempt even happened at all, then no, you wouldn't find out anything. Like, made up example, but if Zorana looks into a dark room and goes "That looks suspicious, I am not going in there, I'm leaving" and leaves, then there's no proof that anyone tried to kill her so nothing gets investigated. If she walks into a dark room, someone jumps her, and she manages to wrestle her attacker into submission, THEN there would be a scene afterwards where security investigates and finds out who was responsible. The investigation is automatic, you don't have to choose anything. Does that make sense?
