The Big Bang Theory Season 6 Episodes

24 Episodes 2012 - 2013

Relationships are the name of the game in the sitcom's sixth season. Howard (Simon Helberg) and Bernadette (Melissa Rauch) begin their married life with Howard on the International Space Station. When he returns, the two of them move out of his mother's house and into their own apartment. Meanwhile, Penny (Kaley Cuoco) and Leonard (Johnny Galecki) work on their on-again, off-again relationship; and Sheldon (Jim Parsons) and Amy (Mayim Bialik) push their boundaries. Comic-book store owner Stuart (Kevin Sussman) has a bigger role this season, as he begins to hang with the group more regularly in Howard's absence.
