Kaiba nods, finally shifting his gaze to Yuugi, to get a better look. He...doesn't look as terrible as Kaiba would have expected from a man who collapsed in a coffee shop. This should go fine.

Something though, something catches in his mind, and he frowns, brows furrowing. Something feels different, and he could have sworn...

No.

No, it's nothing. He clears his throat quietly, then turns away.

"Understood. I'll take care of it."

He walks to the door, ready to summon a nurse or a doctor to attend to Yuugi...but then he pauses.

"I invite you to my home for the night. Consider it."

And then he's gone, before Yuugi can say anything at all. He'll expect an answer when he gets back, but even saying those words was as difficult as assembling a prototype for which you have no point of reference, and he needs space, thanks.
