There's a warmth that surrounds them, a tiny piece of someone there but distant; the knowledge that gets shared that he is waiting for them to come back, like a thread pulling them in the proper direction. Some of the bond spills over with direct contact; something bright waving for attention, and sending encouragement, followed by a warning. Hopefully Tidus has a better translation manual handy because Esteban's words don't make it that far to someone whom he hasn't interacted with before.

But it feels steady, and confident. A promise that they will be safe.
