While only being privy to one side of this conversation, Tidus's behaviour is.. well, it's something. The way the other suddenly seems to fluster, including the accidental banging of his head against the floor. The weird parts of conversations Inigo is picking up on, only barely not enough to make out what exactly is going on here. He just stares down at Tidus, slowly pulling his hand off the other's face.

(Maybe that will help calm Tidus down a little?)

But the words are still puzzling, and they still buzz around in his head.

"Wait, did you two--" Who's kissing? Esteban?! Did they hook up the moment Inigo disappeared?! "Or did you tell him--"

Bro, he leaves the train for.. well, Inigo has no idea how long exactly it's been. A few days? Maybe a week or two at worst?! And what do you do while he's gone?!

At least Inigo makes an attempt to calm down. He doesn't want to freak out Tidus even further, even though Inigo himself is so confused right now. And if Esteban is watching all of this without being able to interact with Inigo, then he can imagine it getting kind of awkward for the other too.

So he shakes his head and stops hovering over Tidus, instead moving to sit. He glances around him, and then starts frowning before he continues.

"Let's.. Let's just go back first." It's better to sort out all of his thoughts later. To have a proper reunion back on the train, once they're sure that they're all safe. In the middle of all this chaos, Inigo hasn't even had the time to process the relief of seeing someone from the train again who didn't leave, nor the gratitude towards these two for helping him.

It'll have to wait a moment. This is more important, right? Stupid fluster aside or not.

".. Can you help me get back..?"
