According to the official synopsis, Amy and Penny take Leonard and Sheldon shopping while Raj worries about his contribution to the operation of a space probe.

The genius duo start to play an invisible board game and end up talking about how much they compromise for each other.
They also talk about how Leonard hasn't moved in with Penny because the last time he mentioned it, Sheldon ran away, and how he can't think of a life without his best friend in it.
Going by reports, they both start crying and Sheldon tells him that he should move out if he really wants to. They later agree that Leonard will do it in stages.
The episode ends with Leonard and Penny celebrating their new life together in Penny's apartment. Sheldon sleeping on the couch calls out for them to keep the noise down.
