Will they? Won't they?

Season four kicks off after Gretchen accepted Jimmy's marriage proposal, only to see him leave her stranded in the Hollywood Hills after he freaked out that she would be his family. Now broken up and involved with other people, Jimmy and Gretchen struggle to move on while constantly being pulled back toward one another.

After a whirlwind courtship and rough post-cohabitation period, Jimmy and Gretchen try to keep the good times rolling while confronting the f-word—“family”.

In Season 2, Jimmy and Gretchen are forced to take their relationship to the next level by moving in together.

Meet Gretchen and Jimmy. She's a cynical PR rep and he's a narcissistic British novelist. Impressed by each other's bad behavior at Jimmy's ex-girlfriend's wedding, they begin what they swear is a casual sexual relationship—until it turns out to be more than that.
