CBS has released a new sneak peek clip of the upcoming finale episode of The Big Bang Theory, and the episode looks to be a significant one. After Leonard and Penny (Kaley Cuoco) got engaged in the latest episode of the sitcom, he may be ready to move out of the apartment he has shared with Sheldon for years.

"How dare the university force me to go back to string theory!" he says, outraged. Amy responds, "They don't appreciate you."

However, it is when he speaks about best friend Leonard that things really get tense.

"Leonard has the audacity to suggest that now that he and Penny are engaged he may not wanna live with me anymore!" he says, clearly under a lot of stress.

Amy notes that it may not be such a bad thing if Leonard wants to move out, listing off various grievances that Sheldon has had with him over the years. These include the fact that Leonard turns up the thermostat when Sheldon's not there as well as the many keys on his keychain.

As Leonard and Penny are fully committing to each other, could Leonard and Sheldon be breaking apart soon?

The Big Bang Theory season 7 airs Thursdays at 8 p.m. on CBS.
