In the finale of The Big Bang Theory, all major characters got their happily-ever-afters except for Raj, who remained single. Even Priya, Raj's sister and Leonard's ex-girlfriend, got married, but her wedding was not mentioned in the show. Priya had a history with the guys dating back to 2005 when Leonard broke the code by having a sexual relationship with her. They restarted their affair years later but ultimately cheated on each other, marking the official end of their relationship. Priya's final physical appearance was in season 5, and she was never shown on-screen again, although she has been mentioned a few times since.
