It's easier with where Tidus is; he grabs at Inigo from behind as Esteban starts to let him go, and the drop isn't too far, not the bed so hard as to really disturb Inigo. Even without the advantage they have on their side: that Inigo is completely out of it.

So he lays, curls, and Tidus watches him for a moment; sets a hand on Inigo's shoulder before he straightens himself enough to look at Esteban.

"Let's go. He's fast out."

There wasn't any reason to stay - not when they had plenty more people to find, and bring back aboard.
