It's a tease, of course. Partially. From what Sirius has seen already, he knows this man is powerful, but Sirius is equally aware of his own prowess.

He's still smiling as they reach the door of the tavern and Sirius holds the door for Kell before following him inside. "Are you from England then?" he asks as they head toward a table near the far wall. "Or from some other world entirely, yet somehow blessed with the proper manner of speaking like some others I've met here."
