[Oh right, that. At the very least, Shun considers that a victory in the sense that he wasn't completely caught out in ignorance, and with that comment he can piece together a better idea of what it is he missed. Which is exactly why he tilts his head up a bit in the manner he does when he's trying to be intimidating, as if Ren's the one who lost the conversation here and not him, because he can still try to preserve some pride out of this exchange.]

Then that just means we both think you need it, and it's at least worth adding to see if it works.

[Unfortunately, Shun has a much easier sidestep for the second question, tilting one of his hands and Ren's wrist with it.]

Shouldn't I be asking you that question, if you've worn yourself out just from that basic a move? [Definitely nailed the reason for the pulse rate rise there.]
