Taub tells the mother that the dad wouldn't come to the door. BEEP BEEP BEEP! It's a pleural effusion! Park says he's bleeding into his lungs! The caption says, "[hyperventilating]" and "[whimpering]" so you know things are serious. The goop coming out the end of the tube is not red, so Park announces that it's not his bone marrow. It's his liver!
House has someone working on his ankle monitor. This involves poking at it with a length of metal. House speculates about the causes for the liver failure, and also about why the mother lied about the biodad's death. Park asks, "This is how you plan to get to the boxing game?" This stops everyone dead. House: "Match, bout, fight, contest, day, Helena. Almost anything works after the word 'boxing.'" That alone justifies this whole episode. Adams thinks the ankle monitor isn't going to be easily busted, but the ankle guy snorts derisively. Ankle guy says the sensor works off heat, not force. So he'll just pop the rivets and slide in a heating pad. Easy! Taub wants to tell Ben about his father being alive. Park says it's not medically relevant and anyway, Ben's a minor. I love Park's defining character trait being the only person who understands that the patients' personal lives aren't necessarily their business. House's ankle thing starts beeping (BEEP BEEP BEEP!) and ankle guy runs off. House pulls the metal stick out of the ankle monitor. He starts to leave and then makes up a plan that has the risk of coma and death. But it tests for two things at once, so it's totally his sort of thing.
Two policemen and Foreman follow a beeping tracker (or a tracking beeper) to a room where House is blithely soaking his feet in a bathtub. He acts shocked that the water caused problems with the ankle monitor.
Taub admits that he might be a little out of bounds as he encourages the mother to tell Ben about his father. She says that Mitchell (that's the biological father) is not Ben's father any more than a sperm donor would have been. She's mad about Ben dropping out of school. She's also mad about Taub nosing in.
A woman comes into House's office while he's poking at his ankle monitor again. He doesn't do a lot of actual work, does he? She's the wife of the diabetes guy. She wants to inject something innocuous into his thigh, but House declines to give her an imaginary prescription.
