The Thespian Catalyst
Sheldon guest lectures at a university, but his teaching style is considered boring and intolerable, and results in negative online feedback from his students. On Amy’s advice, he decides to take acting lessons from Penny for $40 to learn how to more easily communicate with his students, though his attitude during the lessons frustrates Penny. Finally, they act out a Star Trek fanfiction script which Sheldon wrote in his childhood, in which Mr. Spock takes a young Sheldon to the 23rd century to bring hope and peace to the galaxy. Penny plays the role of Spock as she feels that Sheldon needs to come out of his comfort zone, while Sheldon plays the dual role of himself and his mother. However while acting out the script, Sheldon immerses himself so deeply in the part that he is brought to tears, because he does not want to be taken away from his mother by Spock. Penny then calls his mother and gives the phone to Sheldon so that his mother can console him. Meanwhile, Raj develops a crush on Bernadette after she comforts him over not having female company. He starts daydreaming various scenarios involving him and Bernadette; the first one is Howard asking him to satisfy Bernadette’s sexual needs while he is away on a fellowship in Israel; the second one is a dying Howard, who has met with a fatal accident, asking him to take care of Bernadette and satisfy her sexually after his death; the third and final one has him and Bernadette dancing Bollywood-style.
