There's a number of reasons why she wants to fight this dude currently. To test her mettle, for Stede's sake, for the old adage of 'pick a fight with the biggest guy in the yard to show you're hot shit'. But he seems to take her request seriously, not scoffing at her age or gender, and that earns him just the slightest bit of respect in her books.

"Ghost crew?" she asks, then wrinkles her face up, "if you mean the ghosts, then you're fine. They only exist to serve drinks and meals, I don't think they can even leave their stations. Anyone you actually meet is a passenger, and we're not dead. Mostly. We can find somewhere quieter, if it'd make you feel better."
