The privacy afforded to the brothers was used to hug one another at first, followed by Kaiba apologizing ineffectually and Mokuba biting his head off, as he knew he well deserved.

But deserving doesn't mean relenting entirely. He'd left his affairs in order, after all, which Mokuba was highly unappreciative of, his nerves frayed from overseeing the meeting and then basically yanking Isono by the ear to the car and forcing him to break several laws to get him here.

By the end of it, Mokuba exits looking very nearly as harried as he had walking in, but there's a sense of relief so thick in the air it feels palpable.

To Kaiba's deep annoyance, no amount of strongarming or threats could convince the doctors to discharge him that very day. By the time Yuugi comes back in, Mokuba's washed his hands of his brother's absolute infant behavior and is sitting in the hallway, coordinating the executives via phonecall.

Good luck to Yuugi Mutou as he enters Kaiba's hospital room to hear:

"I've bankrupted companies for less than what you're telling me now!"

Oh hey. Sounds like his voice is coming back, huh?
