Tidus can sympathise. Why didn't the train let everyone have magical storage space anymore? There were work-arounds at least, and he's about to mention a name, when another gets shared with him first -- or rather, a hand does.

Which gets a bit of a surprised look, but he takes it with a funny smile, not unaccustomed to shaking hands or anything. Just rare, and he gives Xehanort a nod all the same. "Ted, huh? Name's Tidus! And say, if you're interested in getting one of those, Wangji - he's one of the Blue leads. You might bump into one of the other Wangjis on board? There's one or two." Or three. "--but he can help you out. Maybe if you make a trade?"

It's somewhere to look in any case, especially if the guy's that interested. Though he nods to where Xehanort's notebook has been placed. "Unless you're saving up for anything already. What're you into?"

Did the notebook have anything relevant to Xehanort's interests? It's Tidus's way of trying to learn more about the guy, all the same.
