He had been working a lot with Professor King over the last couple of weeks with his Deathtoll card to see where the Gate could be opened and they had found a lot of, uh, interesting places. It seemed like the most interesting was still the one he and Kaiba had found though, but whatever. He's sure that the two of them would have breakthrough soon. He was scribbling in a notebook in an empty classroom when Kaiba burst in unannounced and... challenged him to a duel. What.

"Kaiba? Are you okay?" He looked positively maniac. He closed the notebook and stood up, wand out and used to lock the door, so his boyfriend couldn't escape without answering the question.
