As for this one... much has already been said... I'll only add that if Sirin had actually done "something bad," Aristarkh would have become a second Sarabas. Not in terms of "searching for a penis," but in the sense that first he would have lashed out at Clarissa, "Where the hell did you send me, you old hag?", and then at Lerad, "Who the fuck is running excavations in your clan?". I don't know what the outcome would have been, but unlike Revan, I wouldn't have created a new character or played as a "skeleton"...
