But then i thought that perhaps she doesn't trust Hao enough to do that...
Right, part of what I'm thinking.
Hao is kind of rolling his eyes at all of this, even the lost kid (For some OOC knowledge; he was a slave as a child and burned down his master's estate, with his master inside, at the age of about 11. That is why he comes off as callous about the missing child quest, "A soft city kid went missing in the woods, boo-hoo."). He may be thinking, "An unpaid tab? I may get a chance to have a nice brawl (playing to background: "To me, a bar fight is a nice way to get to know a new city.") and get in good with the local tavern."
I just wanted to make sure the rest of y'all, as players, are ok with splitting the party and Hao going off. He likely would have walked away from the group without even saying anything. While Xadania is the "leader" by default right now, there is no hierarchy in place that Hao would feel the need to respect (and he would respect an actual organizational hierarchy; rank is very important at sea, even among pirates).
