It's only by moments that Kaiba passes out before Yuugi. Not that it matters. The experiment has yielded its results, and so the two of them are put back into their solitary cell after they're both unconscious and therefore easier to move.

This time, Kaiba's the first to wake, his throat aching miserably when he comes around. Reaching up to feel at it makes his fingers twitch away from the swollen flesh. Obviously he still can't speak, but it even hurts to swallow or draw breath now.

He sits up, glaring at nothing with an inconsolable rage written all over his face.

He doesn't notice what's been left in the room with them yet--a single plate with a cupcake just slightly larger than standard. Large enough to make out the words "Thanks for the Light!" lovingly iced atop it.
