There's a note in the back of Tidus' mind, a reminder to ask the stranger what his theories are on the tethers-- train, tethers, ministry; Esteban hasn't let go of the need to figure things out, not after all that they have seen. He's not smart though, and it might take him a while, but he is willing to get more people in the discussion, asking questions and curious as to how others perceive the train, how they understand it.

But for now, he's more than ready to pull at Tidus-- after their rather chaotic first attempt, they're getting a better grip of the line between them, both a limitation and an anchor-- and Esteban reaches his hand across to Tidus, guiding him back, his location steady, light nudges and memories set as signposts on their path.
