Kumar does an echocardiogram of Sophia's heart. She's annoyed that they're checking for drug use damage, and thinks that they think she needs drugs to ease the pain of being alone at such a young age. Kumar says it must be hard feeling like there's no one to "back you up." Sophia says she doesn't want to do the "pity thing." Kumar finishes up and says he was actually doing the "I get it" thing, as he does with all patients who are orphans, which is kind of a lot of them, really. New Jersey has the highest amount of toxic waste dumps in the country and, it would appear, the highest amount of orphans. Coincidence? "It gets easier. You learn to deal," Kumar says. Sophia softens and says she still gets nervous every time there's a knock at the door, although I don't know why. It's not like there's any more bad news to get, right? Now a knock at the door can only mean good things, like flowers. Kumar says Sophia's heart looks healthy, which means they still don't know what's wrong with her.

Meanwhile, Hadley and Taub are in Sophia's apartment, which has been kept up quite nicely with furniture that she apparently makes herself. Taub notes that even her checkbook is balanced, and I start to wonder if we haven't gone back in time again. I'm no 16-year-old living on my own, but I do live on my own and I don't balance my checkbook. I don't need to. I use online banking and don't write very many checks in the first place these days. Taub wonders what Sophia will be like at age 30 if she's this grown-up at age 16. "You turn back into a kid. Like Kumar," Hadley judges. Um, okay, so Kumar might eat sugary cereal and watch TV, but he's more of an adult than you, Hadley, with your little rebellious sex drug party phase. Hadley whines that Kumar wants to see the best in everyone. Wow, how childish of him. Hadley thinks he's too trusting. Good for him; that just means he's never had to deal with anyone who would cause him to question putting trust in people. Taub says that the other side of that is not trusting enough, which is just as bad. "Excuse me if I don't take relationship advice from you," Hadley snarls. Ugh, she's so unpleasant. Can you imagine having to work with someone like that? If I were Taub, I'd be giving money to Huntington's. Not the research to find a cure foundation, but the disease itself. To find ways of making it bigger, faster, stronger, and prone to making its victims lose the ability to communicate as one of its first symptoms. "Trust should be earned," Hadley says, producing some drug paraphernalia. I guess we're supposed to think it came from Sophia's apartment, but I'm pretty sure it fell out of Hadley's coat pocket.
