His expression settled into a stern frown as the man speaks, disapproval radiating from him. So not only is this man absolutely barmy, but he's intent on starting an altercation: With Ignis, or anyone else. Teeth gritting, he lets out an irritated huff, continuing his step backwards away from the case of knives, and closer to the aisle opposite it.

"And what good would that do you?" He huffs out the question even as he shoots out a hand to to another display case, grasping a weapon of his own.

...Granted, it's a long, flexible fishing rod of all things, unstrung and shiny new, but it's better than being completely without. Besides, he's quite familiar with them, given Noct's passion, and the whip-like quality and reach might be a benefit to him, given the other man's stance. (It's the benefit of using knives himself. Holding the blade in a reverse grip was good for a multitude of reasons, but lacked the same reach as an extended knife. And so, he'll take that advantage and run with it.)

He whips the fishing rod out almost as one would a katana, stance shifting minutely. "I have no quarrel with you, you know. There's nothing to be gained from this." And yet, his every fiber is evident in being focused and ready to parry or defend-- after all, at this point, there's no sense in trying to be subtle. He'll await the first strike.
