And about the Wedge thing. I donno. If I was in his position I would leave as ordered too. But Wedge says "I'm hit, I can't stay with you." and then Luke says "Get clear Wedge, you can't do any more good back there." It seems like Wedge was trying to bail even before Luke gave him the order to leave.
And this has always bothered me because Wedge is just an awesome character. I love him, man. But he did seem to want to chicken out after he was hit and when Luke gave the order his "Sorry." didn't sound like he was all that sorry.
Far be it for me to criticize someone in a combat zone when one's life is at stake. Who knows, I might have done the same thing, but Wedge did seem pretty adimate about wanting to get out of there. I donno.
