Penny, Leonard, and Raj have coffee together in the kitchen. With Raj now living in Sheldon's old room, a lot of things are bound to change in that apartment.
Raj and Penny adjust to their new living arrangement on The Big Bang Theory. "The Collaboration Fluctuation" is the 19th episode of the show's tenth season.
It's just a casual, relaxing morning, and Penny enjoys a cup of coffee. But her mother-in-law is coming to visit, so that relaxation likely won't last.
Sheldon: I'll have a diet Coke. Penny: Can you please order a cocktail? I need to practice mixing drinks. Sheldon: Fine... I'll have a virgin Cuba Libre. Penny: That's... rum and Coke without the rum. Sheldon: Yes, and would you make it diet?
