Science, mostly. And seeing how far I can push my BS meter. Another question: If you don't remember if you told him to sleep it off (hell I cannot even remember the quest/conversation) can you continue to flirt with him and possibly still be romancing him? Or can you not flirt with him at all if the romance isn't on? I'm just confused because I haven't really gotten any sort of "relationship" type conversation with him, just a few 'rescue my friends' quests and he's over 7000 affection and I'm level 38 in the midst of chapter 2. Blarg! I wish there was like SOME sort of icon change to indicate to the player whether you're in fight or in romance or into or whatever with the companions. -.-

Do I have to save his cousin? Can I just let her make her own choices or will not letting him save her screw up a romance with him?

Actually, Vector has something interesting (and funny) to say to the Imp Agent during that whole thing. I was initially concerned, but it turned out great.
