By the time that Yuugi takes hold of his hand, Kaiba's already surrendered to the pitch black of unconsciousness. In fairness, he was already weakened by his revival.

The next time he awakens, it's in a chair, with the weight of something hard and scratchy secured around his neck. It takes him a moment to come to his senses and stop his own head from lolling tiredly against one shoulder. Longer still for his vision to clear.

When it does, he immediately flinches at the sight.

A gallows before him, with Yuugi secured in place with a noose of his own, as well as a loop around his shoulders, keeping him in place and not liable to fall until he came around. Then, when he does, the rope falls away, leaving him supported on his feet with the rope threateningly snug around his throat.

Just like Kaiba's, although his fed to the ground, and there was an array of buttons laid out before him, just within reach to be tapped by one foot. 26 buttons. Each marked with a letter.

This is a game Kaiba has played before.

This is a game he didn't want to play again.

But the scientists didn't care, did they? They wanted to see these two play together, didn't they?

When Yuugi wakes up, there'll be a display visible to both of them showing the rules, cheerily set forth by Helios. And then...it's up to them.
