[Headpats get!! He happily accepts them, taking full advantage of the fact that his brother wasn't monopolizing all of the attention for once. Not that Amane doesn't also get Ai all to himself while in the Dream Sphere, but... it was different in the Waking World, okay!! Still, at the mention of his twin, he can't help but mumble a bit petulantly:]

I dunno why he wanted me to come along with him if that's all he wanted to do, though...

[It'd be one thing if Tsukasa wanted Amane to chat and keep him company as he scratched out all of the little wafers, but if he wasn't even going to acknowledge the fact that he was there...

... well. He couldn't exactly be surprised by this outcome, but he figured his sibling would have gotten better at dividing his attention over the years, too. Maybe that was too much to hope for, though.

Any grumpiness at his brother's fixation is driven away by Ai's suggestion, however, and he beams brightly in response.]

Yeah! I mean, knowing him, he'll probably be here for the next couple hours, so I'm sure he won't mind.

[He extracts himself from the hug at last, moving to collect his bag and other belongings from the table so he could be ready to join her in wandering about. He's smart enough not to directly acknowledge the "we" in that earlier statement of hers-- especially not here in public-- but he can't help but ask, regardless:]

You guys all came together though, huh? It wasn't too much trouble for you, was it?
