As interesting as Bruce is, Martel only has so much time in a day and only so much inclination to expend effort on someone so stubborn when there's no true purpose or gain to it - so with a mildly amused air, he says, "Try 'Aloysius Martel'," as he moves on.

(He doesn't say he does intend to pass the same thing onto the other man in question, but it's only a reasonable precaution.)
