Ep 13. The Solo Oscillation

The episode starts with Sheldon and Amy's apartment, where Amy is starting a week-long fellowship at Princeton University. Sheldon is not accompanying her as he has work to do at his lab, and he's also excited about having some alone time. After Amy leaves, Sheldon starts to enjoy his solo time at the apartment, which includes playing bongos, eating pizza, and watching his favorite TV shows.

Meanwhile, Howard and Raj are planning to attend a magic show. Howard has a limited edition magic trick, and he's willing to pay a lot of money to get his hands on a rare component that would make the trick work. However, the seller lives in the same building as Sheldon, which leads Raj and Howard to visit Sheldon while they're on their way to the magic show.

During their visit, Sheldon reveals to Howard and Raj that he's thrilled to have some alone time. However, after a few hours, Sheldon starts to feel lonely, and his behavior becomes erratic. He starts talking to himself, writing on the walls, and having imaginary conversations with Amy. Raj and Howard realize that Sheldon is struggling to cope with Amy's absence.

At his lab, Sheldon continues to act strangely, and his colleagues are worried about him. He confides in his colleague, Dr. Pemberton, that he'll need to adapt to living alone, given Amy's successful career. Dr. Pemberton suggests that Sheldon should try "solo oscillation," which means spending time alone without distractions. Sheldon decides to give it a try.

Back at the apartment, Sheldon starts practicing solo oscillation, but it doesn't go well. He tries to read a book, but he can't concentrate. He tries to exercise, but he gets injured. Eventually, Sheldon realizes that he can't survive without Amy, and he decides to visit her at Princeton. He apologizes for being a burden and tells her that he's willing to do whatever it takes to make their relationship work.

The episode ends with both of them sharing a moment of understanding as they embrace each other.

In conclusion, The Solo Oscillation is a touching episode that shows the struggles of living apart from your partner and the importance of communication and understanding in a relationship. The episode is filled with humor, heartwarming moments, and a lot of character development, making it a must-watch for fans of the show.
