Oh, look at that face.

It's dawning realisation. It's the cogs of his brain a-turning, the sweet nectar as one opens their eyes and sees the truth. The whole picture. Tidus doesn't want to gloat in that reaction, but the moment Roland's face drops so evidently, there's a rush in him. Look. Look at him go!

And to be fair, it's not a misery Tidus wants to bask or soak in, no matter what others may think. ...okay, maybe he has expectations, but look. It's not about misery. It's about the expectation, and Tidus will argue 'til the fish swim off that it is.

Except--that expression picks back up. The instructions with it. And that. Thing. With Roland's hands. What?? Did he mimic guns?? It's a puzzling change from what just was, and is this a cover-up? Roland realising the truth, even if he isn't giving him any particular looks (because hey, knows out of the two who'd be thought to be the mastermind--and it's not everyday he gets to be one, y'know!). It doesn't make Tidus any less suspicious, but he's far more giddy, smirking. Watching this dork of a guy, cheerful threat.

He puts a hand on his waist, leans back on his own two feet.

"Like t'see ya try," he drawls challengingly.
