In a living room playing chess, Adam and Jane debate if NASA would spend billions to save one astronaut stranded on Mars.

Jane concedes that Benson might share Adam's optimism, but he points out that she went crazy, and we see another astronaut's remains nearby.

She confesses she adapted four power drills into dildos, admits she has considered sex with him and is sure he finds her attractive.

Both watch their spouses' video messages, Adam hoping that his politician aspiring wife Savannah has not waited for him and Jane knowing her sedentary Tom would have loved being there.

As Jane and Tom chat in bed, she admits dancing with Adam was her favorite part of being in space.

Initially when Jane suggests a trip, Tom resists, but relents upon remembering she had been closed in for years.

So at home, when she discovers Tom had been regularly seeing Amber, she insists he contact her, then confesses her and Adam's sexual relationship.

At the White House dinner nine days after their return, Jane tells Adam and Savannah she split with Tom.
