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 probably has a lot of advice for Raj when it comes to living with Leonard and Penny. He'll probably also encourage him to sign a roommate agreement.
