[Amane's so preoccupied with the lingering pain from his fall and trying to figure out their next course of action that he doesn't even catch what Illya's doing until she speaks up-- and promptly freezes on the spot. It goes without saying that he's not really used to interacting with others his own age, let alone girls, so for one to be grabbing his arm like that out of the blue...]

Ah--

[His cheeks and ear flush pink, his eyes darting to her hands, and then her face, and then back, trying to figure out just what was going on. She said she wasn't hurt from the fall, so she probably wasn't using him for support (not that he'd be that good at it at the moment anyway), so-- was this for him? Was she trying to prop him up somehow? His track record with peers his age only ran as far as his twin brother, and Tsukasa probably would have dragged him along by the arm if they were in a similar scenario (not that he expected Illya to do that, of course), so...

He clears his throat a little awkwardly, not entirely sure whether he should remove his arm from her grasp or just accept the help she was tentatively trying to offer. If she was an adult, it'd be one thing, but would it come off as too weird if was a classmate he barely knew?? Not to mention she already sounded surprised at his offer to send them both home, so was that also?? Overstepping a line somehow?? He wasn't even sure at this point, but--]

W-Well, if we're headed the same way, then I don't see why not? I mean... it'd probably be faster than waiting for the buses and dealing with that again. ["That" being the crowd of people already clumping up in anticipation for the next ride] You could always pay me back at school, if that's what you're worried about...?

[Unless it was riding with him she was concerned about, which... to be honest, considering he looked and felt like a wet cat at the moment, he wouldn't really want to sit in a car with himself, either.]
