His eyes follow Taiki's, but only for a second, before he grins and gives the shoulder a roll.

"Good as new! It bled worse than it was." Nothing that a potion couldn't stitch back together. That's how his life's become; sealing away the wounds he goes through like they never happened, ready to fight another day. "Sorry I made you get involved with me and my dad. I knew he was an illusion..."

But he doesn't want to talk about that now, not with Taiki's face so flushed. There's something else on his mind, and Tidus moves around the hand that Taiki holds, offering his other with a "Hold on" muttered, so he can free the one with his arms band around the wrist. It takes a second for him to concentrate, and a small bottle appears; a cloudy but otherwise clear liquid inside.

"Do you want to try this, for your sickness? It's a remedy... it's meant to be a good for a lot of things - maybe it'll do your fever some good."

It's a bit difficult to explain, but only because he just knows it as being 'good for most things'. Will it work? Tidus doesn't know, but he wants to try anyway, to give Taiki some comfort.
