Kaiba doesn't realize anything's amiss. He's just having a conversation with Yuugi, being incredibly kind for someone like him, and not worrying about the strangeness of things around them.

Everything always got strange when Pegasus was involved. He was always thrown off-kilter, and a stain on his jacket doesn't really qualify as the weirdest thing he's ever had to deal with during times like that.

While Yuugi's texting, he taps on his bracer, having the cameras sweep for where Pegasus was malingering. Evidently, he was near the front door already, with Mokuba. Good. Then it's about that time.

"You should probably get your affairs straightened for the day. We'll be leaving soon."

He sounds sooooo excited about it.

For his part, Mokuba takes a moment between Pegasus's nattering to check his texts...sees the one from Yuugi and frowns, before tapping out a quick response.

Seto always gets weird around him. I wish I could say it's surprising but

I mean, I guess that is actually super weird, even for him.

Behind him, Pegasus frowns imperceptibly.
