There's a restlessness about Tidus, a form of something unspoken in himself in the way his eyes rest on Elidibus, particularly at the mention of Xehanort, and then cast aside. The purse of his lips that comes and then eases. I wish you well, he says, and Tidus tips his head slightly.

"...Yeah," he says with some small sigh, looks back at Elidibus - sad, but maybe regretful. "You too. I'll pass on your message, for sure."

Even if he and the other guy hadn't last spoken on good terms, either - but such was the nature of the train, and life. But Tidus gives Elidibus one last nod of his head, and he'll step back, to continue on his way.
