Trying is all Tidus can ask for. Or letting the knowledge wash over Inigo more, let it have time to sink in when Tidus has only just been able to assuage that fear and belief any. He hopes. He really, really hopes.

So he answers Inigo's idea with a "Sure," to sit together quietly. But even so, Tidus knows right away that wouldn't have been possible. Not before, and now, he isn't so sure; what he wants, and what he'll be able to give. How will be like once he returns on the train? The mission didn't give him answers, though it helped in its own terrible, awful way.

"...I...didn't think I deserved to be around anyone. To be honest, I hurt Taiki too," he admits, and that makes the lump in his throat harder. Tidus breathes out, nosily, really not wanting to fall apart; shifting his arms to hold around Inigo just in the way he needs to, right then.

"I know I have a lot I need to say," to explain, to be honest about, "but I... I need more time. Just to think."

And there's more he wants to say, but he holds his tongue from the rambling, too uncertain of where it'll lead.
