6 - 1: The Date Night Variable

Sheldon and Amy have a date and Leonard and Penny have a date, but Sheldon invites Raj to his date, upsetting Amy. As a result, Raj interrupts Leonard and Penny's, only to get kicked out when he tells Penny to acknowledge her feelings for Leonard, prompting him to go to the comic book store instead, where he gets himself in a sort-of date with Stuart. Meanwhile, a still-in-space Howard gets in a dilemma with his wife and mother over where he will choose to live once he returns to Earth.
