Stills from the first two episodes of The Big Bang Theory season 7 hint that the season will be kicking off with a sleepover, a reunion, and a Stuart.

The Big Bang Theory season 7 premiere will include the first two episodes of the season. New stills from CBS give us a look at what the geeky gang will be up to once the new season hits our TV screens.

First check out the photos from episode 7×01, “The Hofstadter Insufficiency,” which show Sheldon and Penny coping with Leonard-withdrawal as the scientist/boyfriend in question sails the North Sea.

We also get a fun glimpse of what looks like an Amy/Bernadette sleepover. It will be interesting to see the two ladies hanging out without Penny – and we hope Bernadette knows what she’s getting herself into!

The official summary for “The Hofstadter Insufficiency” says:

With Leonard away, Sheldon and Penny spend quality time together sharing intimate secrets. Also, Wolowitz helps Raj get over his ex-girlfriend.

Regina King will return as Ms. Davis, the University’s Head of Employee Relations.

Next, check out the big crop of stills from episode 7×02, “The Deception Verification,” in which Leonard returns and Howard hugs a pillow.

Couples seem to be the name of the game in this one, as Sheldon and Amy, Leonard and Penny, and Howard and Bernadette all appear to spending quality time with each other. And even hard-luck comic book store owner Stuart (Kevin Sussman) is back, perhaps to rekindle his bromance with Raj from last season.

The summary for “The Deception Verification” tells us that:

Leonard’s friendship with Sheldon is put to the test when he returns from the North Sea. Meanwhile, Wolowitz’s relationship with his mother causes an unusual threat to his masculinity.

You can also check out this brief – but powerful – promo for The Big Bang Theory season 7 premiere, which makes us grateful that Leonard does, in fact, return from his extended field trip.

The Big Bang Theory season 7 premiers at 8 pm on Sept. 26 on CBS.
