In rehab, Jackie escapes to a broom closet for some solitude, only to find the 17-year-old Charlie.

Worried about Grace, Jackie leaves rehab early against the medical advice of her counselor and returns to a very different All Saints. On top of the Quantam Bay takeover, this is the first time she's had to work sober. Almost instantly her nerves are rattled, and even Coop hurts her feelings.

When Grace reveals she knows about rehab, Jackie is blindsided, and goes to Kevin's to make sure he's aware of everything before he hears it from someone else.

Jackie, making pancakes for the girls, realizes too late that the girls aren't even home--they're with Kevin. At O'Hara's apartment, she admits that she's not adjusting well to living alone and, against O'Hara's advice, decides to call Kevin and invite him to lunch.

Jackie wakes from a vivid dream about sex with Cruz and using again. Kevin, suing for full custody, prompts O'Hara to take action on Jackie's behalf. Jackie and Zoey grow accustomed to their new living situation at the Peyton home, and "co-parenting" duties. Jackie, O'Hara and Akalitus work as a team while treating a transgender teen.
