"I promise!" It's quick, flustered to a degree; not wanting to be misunderstood, lips slightly parted as he works his brain around Roland's request, the hand on his shoulder.

"That's what I mean - I won't let the info go away. Yours or mine, or anything we learn. We'll put it all down, stick it in the library. On paper, or on a tablet." A promise, reassurance, though it wasn't clear the first time round. Tidus looks at Roland with the awkwardness of a guy not used to such a weight or responsibility, not sure what to do with it, but trying his best.

"But you have to promise the same too, alright? Any one of us can disappear. We'll let people know - we won't let anything disappear if we do."

And he returns the gesture, reaching out to pat Roland on the arm.

"Okay?"
