[Well, Henry isn't exactly wrong, and Ren's expression becomes a little more thoughtful. In part because he's not entirely sure of the mechanics of magic here, and whether there is a possibility he might be able to learn it.]

Well, yes, but I don't think I'd find exploding people that interesting...I'm sure there are other kinds of magic that would work better for me...

[Dark magic is fine, but if he's going to be casting magic on people he wants to be able to watch them squirm, and blowing them up doesn't really lend itself to that in the slightest.]
