Usually it might be hard to catch what exactly someone is trying to say when it's a longer sentence, but Inigo instantly grasps what Tidus is trying to say. Mostly since he knows Tidus. He knows exactly what the other is trying to convey, even if he wouldn't have mouthed anything. This is so not the moment to no homo this situation up, bro!

Although it makes him doubt too. He really doesn't want to screw this up. Taiki is too important. To both of them, he knows. Which is why he definitely starts to look more unsure of himself, cheeks burning and his gaze darting away to their surroundings before it returns to Tidus. Ugh, what is the right thing to do here?

He shakes his head, looking even more frantic now as he mouths all over again. Just do it!!
