[Akira is a member of the frequent headaches club too, if for very different reasons, so he knows what they look like. Even if he couldn't read minds it'd be apparent that Ryoko's currently suffering from one—she's been quiet for some time now, and the way her brows are knit together, her grumpier than usual, pained expression, and the way her eyes are focused on a singular point of Absolutely Nothing are dead giveaways. They're usually so bad she curls up to clutch her head, so before it can get that bad, Akira figures it's worth trying to intervene where he can.

It's probably not a substitute for her medicine, but he at least wants to try.]

Hey, Ryoko...you don't look too good. Headache?

[The asking is really only a formality, because he barely gives her enough time to answer before he continues:]

Y'know, when I got really bad headaches as a kid, there was something Taeko would do to help...I could try it out for you, if you want.

[He looks a little bashful about it, though—just a twinge of a blush dusting his cheeks.]
