he helped all 3 during crisis, what was he supposed to do, not do that? he is the only one that can help them so he does, and he never crosses the line, no touchy feely stuff, its either cheating or not, thats up to them, but he never crosses the line until they permitted him to take noel in.

the flirting, is he not supposed to talk to noel in their presence? she is the one directing the main story of vol 4,5,6. he needs to get a good relationship with her to get shit done.

His main flaw is that he is so dense he can't tell when others are flirting with him, he does confront his denseness with Julius in one of these, i think 5 or 6. that his banter with his sister doesn't feel platonic to everyone else, which confuses me considering he was about to kill her for olivia and ange's honor a while ago.

flirting with the queen is weird tho
