Kaiba wants to tell him he's wrong. That what he'd done was worse than anything that happened here, and that Yuugi was a fool to trust him. He wanted to tell Yuugi all about Death-T, to paint himself as the villain that he knows he is, deep down, and rail at him for what this other self did to him.

He wanted to scream until his throat bled, to try and make the words have sound, when they won't.

He tries. He tries to type it out.

tHere is no way out,

THEre is no one I can trust

i Cant trust you i cant trust anyone here,

Suddenly, Kaiba's head whips around, as if he expects something to attack him. Like he expects someone at the door, calling his screen name and preparing to strike.

(Catch, Loser!)

It rings out in his ears, and he flings himself away from the desk with the laptop, away from Yuugi, his eyes wide and manic as he dodges--

--nothing.

Nothing at all.

He's in profile to his roommate, now, it'll be harder to read lips this way, but for the force in which he tries to push words out:

Stay away from me! Don't touch me!
