"Yeah okay." Senku agreed first. He yawned, but he totally stifled it, there was no way Tidus saw that.

"Wait..." He blinked a moment. He was forgetting something. What was it...

There was some reason this was a bad idea.

It could be that his hands and wrists were completely bare meaning he wasn't the one with the arms band at the moment, but give him a second Tidus. He might get there.
