Tidus can see the way the event still hangs over Inigo, clings to him, despite some form of reassurance that at least - at least it wasn't risen just filling the streets. A different problem entirely, somehow, but they'll figure that once they understand more. And Inigo for now continues to be shaken in the dry replies that he offers.

And so, once Inigo finishes speaking, Tidus takes a step in to lean in to the SCA, to be the reassurance for Roland, to give it also in place of what Inigo can offer right now without forcing it:

"Don't worry, we'll keep an eye on things here, see what else we find and take it out. You and Ranny take care on your side! We'll talk about everything later - so don't get done in by a bunch of slimes, you hear?"

There's a teasing lilt to the end there, and Tidus glances up at Inigo, offers him a smile and nod.
