“Killian.”  There’s more to it, of course, but given the man’s apparent limited grasp of English, he doesn’t want to cause any confusion.  He’s been called ‘captain’ for so long (and ‘Hook’ for so much longer) that it might be nice to be regularly called Killian again, at least not by someone who shares a bed with him.  He’s not really a captain anymore anyway, with the Jolly Roger stuck in the Enchanted Forest in the hands of Blackbeard, and no idea if he’ll ever see her again, and with being in this strange place that so far as he can tell doesn’t even have an ocean.  (But it must.  How can a place not have an ocean?)

He shakes the hand that’s offered, and finally catches sight of what the other man is holding in his hand.  “Are you making a compass?”  That could definitely be useful.
