I see the Aithusa plot twist in another way actually. When you think about it. Kilgharrah wanted Merlin to save the dragon egg so his kind could keep going, so maybe he lied about Aithusa's destiny/future. Or maybe, because Kilgharrah didn't know there was a dragon egg until Merlin told him, he probably doesn't know how Aithusa will develop.
