[Well he relaxes like, halfway. On the one hand, Firefist Ace isn't an issue. A little surprising, sure, given he's also supposed to be dead, but it's hard to really be surprised by that when he's standing here talking to someone who's supposed to have been dead for longer. Yamato, on the other hand...]

I haven't met either of them but I know who they are. Firefist Ace is the older brother of Strawhat Luffy, whose crew I've made a temporary alliance with.

But Yamato is Kaidou's son. So that could be a problem.
[He opens his mouth to say more, but then realizes he doesn't really want to get into how much trouble he's gotten himself into. Really, Corazon was a marine. He got Law away from Doflamingo probably in the hopes that after he was cured he'd stop pursuing the life of a pirate. Not only did Law do the opposite of that, but now he's in the midst of taking on one of the most dangerous crews in the New World.

So he thinks better of it, his mouth settling into a grim line. As if Corazon isn't going to ask why it's a problem.]
