Eh, true enough. I like to keep a BIT of logic for conversation's sake, though.
Also, about the OotBK defecting, they won't. They realize that at this point they've got the means to destroy the power that brought them so much shit to deal with. At worst, once Britannia's done with, they will, or at least force Lelouch to show his identity if he doesn't do so by his own free will.
