Now a train goes by the house. Irene and Janet have returned. Irene walks across the room and tells Rebecca that she doesn't know what's wrong with her. Rebecca silently hugs Irene. In the background, Janet starts laughing for no reason. Rebecca suggests that they go call a doctor, and Irene agrees. Irene gets on the phone and calls a doctor to whom she was referred. In an interview, Irene says she's scared to go to the doctor because she knows that they will tell her something is wrong. Hey, I had that same fear about the dentist, but trust me on this one -- make an appointment and go.
Irene and Rebecca ride in a cab to see Irene's doctor. Rebecca says that it might be "just a little bit of a relapse." Irene says that it's "a bad situation" because she didn't take an adequate amount of time off after she was diagnosed. In an interview, Rebecca explains that she looked Lyme Disease up on the internet (shout-out?) and it's "a lot more serious than [she] thought." Rebecca explains that it causes "fatigue, nausea, muscle weakening, abdominal pain -- it's a nightmare!"
At the doctor's office, Irene says that she needs a friend to come with her, because she often denies her problems. Rebecca voice-overs that Lyme Disease is fatal in ten percent of cases, and that forty to sixty percent of cases will experience "major muscle deterioration." The doctor comes in, and Irene greets her. The doctor's all, "Um, my chair?" and Rebecca's all, "Oops!" and stands up. In an interview, Irene says that she really appreciates Rebecca's coming with her. Irene describes her symptoms to the doctor, including headaches, hands and feet falling asleep, and excessive bruising. In an interview, Irene says that she's been sick this whole time and didn't know it, and PSAs that "Lyme Disease is the disease in disguise."
Irene and Rebecca leave the doctor's office. In the cab, Irene says that her bigger fear was that there was nothing wrong with her, and that she was going crazy. Irene jokes that it's a relief to be able to say that she has "neuropathy." Irene laughs with relief. In an interview, Irene says that finding out she was sick made everything make sense, including all of her behavior. In the cab, Rebecca continues to joke that Irene can say, "I just have nerve damage! That's good! I'm not going insane!" Irene laughs some more. Irene notes that it's sick that she's so happy to learn there's something wrong with her.
The song on the soundtrack says, "I just don't know what to do." Back at Pier 70, Irene lies in bed. Nathan sits there as she explains her disease, and points out that her feet are asleep. Nathan starts punching her feet, to get them to wake up. Nathan says that he thinks he has nerve damage too, which makes Irene laugh. In an interview, Nathan says that he loves Irene like a sister, and that the more he's learning about Lyme Disease, the more he realizes how sad it is. Because when he thought she was mentally ill or on medication, he hated her. Nice. In a confessional, Irene says she's trying to joke about it, but the truth is that it is serious.
