Kaiba frowns at Yuugi's reaction. Sure, he wasn't overly great at dealing with emotions, but even he could read draconic body language. Debatably even better than he could read actual emotional responses from anyone but his brother.

"I won't stop until I see him again," he says as if it's the most obvious thing in the world. Why would Yuugi ever think he might? Or...perhaps he thinks Kaiba should be content with his lot? More fool him--Yuugi had, again, been allowed to see Atem off! And Kaiba? Well...the pharaoh owed it to him.

"We have unfinished business, that's all."
