Guess what? Son of Donny has no interest in some painful bone marrow biopsy to diagnose a condition he doesn't have to worry about for another thirty years. Cameron pulls Mom outside to talk to her about stuff that has nothing to do with medical treatment, encouraging her to tell Donny's son about his father. "I've been lying to him his whole life. What's he gonna think of me?" Mom says. I guess you should have thought of that before you lied to your son for his whole life, Mom. Cameron urges Mom to do it anyway, pointing out that if Donny is right and does die soon, this could be his son's only chance to meet the father who didn't want him in the first place.
House is on rounds with Dr. Singh and a trio of med students. They gather around a patient's bed and one student and/or resident says she is ready to be released. At that, her vitals crash and alarm bells go off. The students rush to tend to her, sticking their fingers down her throat in their zeal to help. Dr. Singh hangs back and tells House to stop pushing the button on the poor patient's monitor that is making her vitals appear to crash. He does, and she's totally fine. The students are not pleased, since they were about to perform all kinds of emergency life-saving procedures on her. Not to mention the scare of a lifetime that poor patient just got. I like House much better when his childish behavior doesn't come at the expense of helpless sick people. Dr. Singh asks House to stop acting like this and just do the rounds as ordered. House responds by ripping the patient's catheter tube out with his cane, causing her to groan in pain (guess what isn't a pleasant sensation? Having a tube ripped out of your bladder) and spilling urine on the floor. House shoves a paper in Singh's face and urges him to sign off on House's 120 hours before he does worse. Like what, he smacks the patient across the face? I thought House learned how to care about people or something.
The ex-girlfriend tells Donny that he has a son. She was pregnant when they broke up but decided not to tell him because she knew he didn't want kids. And she's not sorry about it at all. Her son wants to meet his father. His father doesn't want to meet him. "Just say hi to him," Mom says. Yeah, that'll be enough. The kid won't ask anything more from his father. This is all very fucked up. The son, whose name we finally learn is Michael, walks in. They exchange awkward hellos, and then Michael asks his father if they can do something together when he gets better. With tears in his eyes, Donny says no. His father died when he was Michael's age and it was "the most painful thing [he] ever went through." Since he thinks he's going to die, too, he wants to spare his son that pain. It's kind of too late, though, since Michael knows his father exists. In fact, this is probably more painful for Michael than having a relationship with Donny and then Donny dying would have been. Anyway, nice going on that one, Cameron.
