The only one that really bothers me is Cid's, just because there's absolutely no reason whatsoever that he couldn't have dropped the bomb overboard without jumping with it. I'm not going to get too critical of the verisimilitude of a game called "Final Fantasy," but the fact that they expect me to believe a man holding a bomb decides "hmmm, I could drop this and save the party. No, I'd better hold onto it and jump with it. Because.... because..... oh, just for the Hell of it, I suppose" ... that's crossing the line. C'mon, meet me halfway here. Have him trip trying to drop it. Something even remotely plausible.
