The swordsman considers this. Obviously, he's greedy for the practical aspects of it; there is a lot that he could do with the ability to move things with only a gesture. Kylo saved his life once, when that house nearly collapsed on him. But there are a great many magic tricks he's seen in this world that would be a lot of fun to try out, and which Kevin won't pursue, because the methods of getting there don't suit him at all. In this case, he's thinking much the same thing that Kylo is. Even if Kevin isn't interested in the man's self-appointed duty of being a sourpuss to offset all the gross friendship going on in this place, much of the underlying ideas in him are ideas that Kevin agrees with. Even the ones that overall seem unpopular.

"...is it something that I could learn?" he asks at length. "The sorts of things you do, I was under the impression it's an ability one is either born with, or isn't."

Otherworlders learning abilities from other worlds entirely is not unheard of even without the benefit of asterisks, and as it's turned out, Kevin isn't a totally average human being. Still, if there's anything about him that would lend itself to this, he doesn't know enough about the Force to recognize it. He wonders vaguely if Kylo would bother to offer this as a joke, or if he's seen something.
