Thursday's episode of "The Big Bang Theory" will see Amy and Sheldon attempting to date others and move on with their lives.

The eighth episode of the season is entitled "The Mystery Date Observation" and it will see Amy going on a date with Dave (guest starring Stephen Merchant), and Sheldon seeking Raj and Howard's help to find a new girlfriend.

It was Raj and Howard who introduced Sheldon to Amy in the first place, and it looks like Sheldon is ready to trust their choice once again.

However, the duo won't go the traditional route this time around. According to a leaked description of the episode, Raj and Howard set up a scavenger hunt type challenge where each woman vying to gain Sheldon's attention will have to complete a set of challenges before his contact information is provided.

Only one woman makes it to the end. "A moment later there is a knock at the door and it is a girl named Vanessa (Analeigh Tipton). They seem to get along well and she enjoyed the challenge, but since she didn't complete the challenge on time Sheldon shuts the door in her face," a description of the scene reads.

As for Amy and her new date, Dave, things don't work out for them as well. It turns out Dave is a major Sheldon fan, and their date starts going downhill when Dave utilises all his time to find out more about Amy's ex.

The official synopsis for "The Mystery Date Observation" reads:

Amy has a formal date which Penny and Bernadette and a reluctant Leonard, secretly spy on. Sheldon has Howard and Raj help him find a new girlfriend since they found Amy for him.
