We were the kings and queens of promise

Lelouch has been a bit confused with Ashe even since her spat with Yzak. While he agrees that Yzak is over the top, it bothers him that she would resort to violence out of pride, even pride for her people/land. This is, unfortunately, Lelouch's general resentment toward nobility rearing its head. He feels she had a clear advantage over Yzak and therefore sees it as bullying, though he does acknowledge that Yzak had his chance to back down. See, Lelouch came to respect Ashe, despite his feelings toward royalty because he did get the feeling that she wanted to be a good queen and that she would be one and that her fire for getting things done would protect her people. He really does like Ashe. But yes, that behavior stirred those old ghosts, and now he's evaluating whether Ashe can control such feelings around those who cannot fight back. He wants to know she can still be responsible since she has to be. Conflicted.
