Impressed, no, but not in a way that suggests he's somehow unimpressed. The idea of seeking out this kind of discipline for any other reason is alien, is the thing, and while he's vaguely acquainted with the notion he's never really given it much thought before. Now seems like as good a time as any to do so and he wonders what drives that, what reasons there are. Violence has defined his life without ever really being something that appeals to him - he's really, really good at it, grown into a role that he doesn't know how to put aside or if he wants to - and it's just an odd thought.

His world and his life aren't much like most here, though; he should look into this a little more. Maybe there's something in it worth knowing. (Or maybe it'll just make him uncomfortable and confused, that's always possible - being openminded doesn't mean not having any of his own hangups.)

"What for, then, if not combat?" Arum training has adapted over generations, because the world changes around them and they've needed new ways to rip parts of it down. A holding pattern doesn't make sense to him, but he's already acknowledged the kind of context he comes from when he approaches it.
