The Big Bang Theory season 7, episode 13 takes off, Sheldon is convinced and paranoid (as always) that the University is making him use his vacation days. Leonard and Penny discuss their fight; Penny doesn’t want to break up, making the very angst Leonard breathe a much needed sigh of relief, however, it’s still the end of an era, as Penny tells him that she has quit her job at the Cheesecake Factory.
Sheldon begs Leonard to take him to work, adopting the role of an overactive puppy, but Leonard leaves him at home.

Though he intends to lie to Penny and acts supportive of her decision to quit her job, the charade is dropped when she says she is at the Cheesecake Factory. Before Leonard can fully breather another sigh of relief, Penny tells him that she was only there to drop off her uniform.
In her car, an angry Penny asks Sheldon if he thinks she’s making a mistake. Sheldon says no; the best way to achieve a goal is to attack it single-mindedly. Later, Penny and Sheldon do yoga, until Leonard gets home.

Things get angry for a while, until Leonard says that while he couldn’t do what Penny is doing, he’s proud of her. Sheldon proposes a celebratory milk shake.
