Ougi used to be the leader of the resistence cell after Kallen's brother died, remember? And he was somewhat good at it. Kallen's the hot-blooded mecha pilot, and thus doesn't know much about tactics and running an army and stuff like that.>>13065185
Lelouch is actually a pretty good pilot, it's just that his matchups usually are:
Sutherland vs Lancelot
Burai vs Lancelot
Gawain (big hulking slow-moving thing) vs Cornellia
Gawain vs Siegfried (over -9000 to hit AC)
He's kicking ass with the Shinkirou now.
