The next morning, Dr. X comes back to the lab. He's not happy with the way things are going, but he's also not angry at Dr. Y. He just wants to know what's going on. The doctor is all, "I don't care what you think of me, I'm just here to do my job" . He doesn't want to get into a fight with Dr. Z. He wants to get to the bottom of the matter. He tells the doctor to go back to his room.
