Read on for more on Dad‘s “colorfully ambivalent” heroine, and for scoop on the Marshall, Lily, Robin and Barney in her life.

SALLY | She’s vibrant, messy and unpredictable — a “female Peter Pan who has never grown up and has no idea of where she’s going in life.” She’s thinking of calling it quits with her husband of a year, Gavin. She’ll lean on her circle of friends for advice and support through the inevitable divorce. That circle includes…

JULIET | Sally’s sexy, flamboyant, energetic, party-girl BFF. She runs a successful fashion blog. She’s delighted to learn Sally is ending things with the terminally boring Gavin.

DANNY | Sally’s older gay brother, a Type A, overachieving lawyer whom she shares little in common with. They nonetheless share a tight bond, although Sally’s decision to move in with Danny after her split with Gavin promises to test that bond.

TODD | Danny’s warm, outgoing husband and one of Sally’s closest friends from college. Unlike Danny, Todd welcomes Sally into their home.

FRANK | The head of IT for Juliet’s fashion blog. He’s a hot nerd. He has genuine feelings for Sally, but it’s a one-sided flirtation. At least for the moment.

NARRATOR | It’s Sally from the future. She’s reliving the events of her past to her kids.
