Lowkey, Imoen was my sis before it was canon she was my sis, so Irenicus messing with her was all the motivation i needed to want to ruin his day, way more than i'd wanted to ruin Sarevok's.

A huge downside of BG2, though, it must be said, that everything hinges so much on Imoen. Main plot doesn't make much sense if one, or one's character, doesn't much care about her.

(Of course BG3 doesn't even have that, since the whole tadpole plot hinges on -- what? how much i care about my newly born character?)
