The Season 7 finale of hit American sitcom The Big Bang Theory, titled The Status Quo Combustion, will air on 15 May on CBS.
The show's executive producer Steve Molaro hinted what the gang will be up to in the last episode.
"There are a lot of moves made by different people in the finale," he told TV Guide. "This season is more of a cliff-hanger ... and what happens affects everyone, not just one person."

The Big Bang Theory Season 7, episode 24
In the preview of the finale, Sheldon is struggling with all the changes in his life.
Meanwhile, Jim Parsons, who plays Dr Sheldon Cooper, said his character will go AWOL (Absent Without Official Leave) by the end of the finale.
"He gets the hell out of there and I have no idea where he's going or what he's planning," he told TVLine.
"I won't know until I come back and read the first episode [of Season 8]."
"All the [personal and professional] changes that are taking place finally start to come home to roost for him as problems," he added.
"It was very interesting to read it for the first time and then to play the final episode because it really gets at the crux of something that is perhaps his defining characteristic as a character on television — which is his resistance to change.
"If you look at it through that lens, so many of the things he does, the things he says, the places he sits, etc, have everything to do with the fact that this is the way it's done, this is the right way to do it and this has served him fairly well as a human. They've got him in a situation now, the writers do, where it's not possible to carry on without some of these changes."
