Excuse me, but I'm not sure what you're talking about. I didn't really comment on Librescu. My feeling is that he appears to have performed a brave act. In the passage above, I was merely calling Michael out on his supposed interest ("I'd quite like to know") in whether or not Librescu had done anything to add to Cho's list of grievances. Weiss obviously doesn't want to know, and the line for him was nothing more than what he imagined was a clever put down. It is perhaps reasonable to guess that Librescu had done nothing to Cho, but because none of us at this point know anything about the background of their relationship, one shouldn't automatically dismiss the notion as an impossibility.
