"They always do end up being at odds, don't they?" He doesn't mean pirates, he means everyone. People of all species and backgrounds. It seems to be the most consistent truth. Jack finds it interesting because his birth father would blame it all on humans, but he knows that it's true of everyone, and now he has proof that's true across worlds. Maybe in a way that can be comforting. Something everyone has in common.

"But I know pirates in legend in particular were. Wars with the navy but with each other too. For more gold." Jack could get a lot of gold if he wanted to but he wouldn't understand the reason behind it. Trust Jack to absorb more information about pirates than he does about most useful things.

He smiles at that idea. "I would like that. Maybe that's what we should say happened." Jack is fine with making up a possible fantasy and calling it truth. Or maybe when he goes home, if he manages to survive his fate, he can go look for himself. The fact he never explored is one of the things he regrets, but death is in the cards. "I am Jack."
