Taub asks Della if she isn't trying to live Hugo's life for him with the skateboarding and the love of science. Della admits that she is, saying she started skateboarding after some of Hugo's friends picked it up since he could never do it. "We live through it together," she says. I'm sorry, but no. No one is like this. Especially not a 14-year-old. Taub asks if she might be taking this selfless thing a bit too far. Della says she's just inspired by her brother. Inspired to do what? Die young? I'll bet if someone told Hugo a bone marrow donation from his sister would save his life, he'd do it. It's hard to care about this girl when she's so unrealistic. Anyway, she's soon coughing up blood, which Taub says is a hemothorax and means it's not amyloidosis. Well. Good thing she wouldn't let them do that bone marrow transplant, then.

While Della's lungs are repaired in the OR, House and Cuddy observe from the observation balcony. House wants to fill Della's lungs with some kind of foam that will apparently stop the bleeding but could also, as Cuddy points out, leave Della with too little lung function to survive. House says they could also try to suture the hole that Della's lungs are bleeding out of, but that might take so long that Della will bleed to death first. Cuddy thinks for a minute before agreeing with House's faster but riskier foam option. She leaves immediately afterwards, and House orders Chase to suture the lung.

House then rushes off to talk to Wilson, admitting that he can't handle Cuddy being his boss after all. Even when she agreed to his lung foaming request, he could do it because deep down, he knew that she was only saying yes because that's what he wanted. Normally, he wouldn't even care why she said yes as long as she bent to his will, (and in some cases, he wouldn't even care if she said yes or no and just did it anyway), but now that they're dating, her feelings actually matter to him. And because of this, House fears, he's going to screw up his case. Wilson says this doesn't have to be a problem as long as House and Cuddy set some "ground rules." House takes that to mean he should find a way to avoid dealing with Cuddy at work entirely. "Thanks," House says. "No problem," Wilson responds, clearly counting down the hours until House returns to his office asking for help because that didn't work.
