She isn't offended, exactly but it is off putting to be told that so bluntly. Thus Gaia blinks a few times before collecting herself and instead responding to the second statement. The care he bestows on Grani almost seems to belie the chill indifference. But she won't let herself be distracted by that.

"It's not that I disbelieve. But it'd be rude to just assume there'd be nothing wanted in return. I also don't like feeling in debt."

Is there any suggestion she would be if she didn't take the offer? None. At least not at the level of getting protection from hidden wild dangers. Yet. But this doesn't mean she can't be candid herself. Introductions are made and her eyes widen a trace.

Gaia knows the concept of a king. Something of the past before the Flood of Light. The elves had one and the Fae still had one in a sense, though probably not in the same way as a mortal ruler.

"...My name is Gaia. And... sorry, are you saying you rule this island then? And... what should I refer to you by if that's the case?"

Having actual kings here might change how she's already started perceiving this place.

"Oh, and I think I'll take the offer for shelter." Animals or not, long wait for the trolley or not. It is getting cold.
