He enters the room where the team is doing medical stuff to the patient. He announces that the trachea wasn't swollen; it was blocked by a pseudomembrane. The patient is not paranoid, but is an idiot who was poisoned by something. He disconnects the doohickey from the patient's chest and pokes a giant machine down his throat hole. It's diphtheria! Because the guy didn't get vaccinated. The audience is left to connect the dots between "won't eat or drink anything he didn't make," "has a lot of guns," and "doesn't believe in vaccinations."
Taub is at the nurse's station. Foreman thinks the diphtheria thing is cool. This scene didn't go anywhere.
Park is working with the patient when Mrs. Patient comes in. She's glad the antitoxin is working, but she and the kids have moved out. She says she can't live in that home. But she isn't leaving him; she won't let him live there either. "It's not worth living in fear." He agrees and apologizes. They hug, but I think he's figuring out where to bury guns in the new backyard.
Foreman works. The nurse encourages him to go to Rudy's and eat nachos with everyone.
Park gets on the elevator with Adams and Chase. She asks Chase out for a drink after work. Not Adams. Just the two of them. Chase thinks Taub might have put her up to it. Nope. He claims they shouldn't because they work together. She points out that he married someone he used to work with. Fine. Drinks tonight, then. Everyone stands in the elevator, looking awkward.
Foreman works. There's snow outside. He grabs his phone and says that he's changed his mind.
House returns his gun to the cigar box in his closet. Then he checks the cool sword that says "John House" on it. It's a cavalry saber, right? I admit that I don't know all the complicated backstory he's built up. That's why I didn't know last episode that Chase had once hypnotized him.
Foreman's at the bar. Anita greets him. Foreman! Making time with a married woman!
