A year ago, Nyla and Lila were at the grocery store when a drug dealer recognized Harper from her undercover work and attacked her. Lila was terrified and Don used the incident to get custody of Lila and to ask that Nyla only had supervised visitation with their daughter.
Harper asks Nolan to come with her as a buffer between her and her ex. Nolan brings Grace. Nolan asks Harper if she thinks it’s a problem that Grace hasn’t introduced him to her son, Oliver. Harper says it means Grace is putting her son’s needs ahead of everyone else’s and she’s a good mom.
Turns out the “ghost” Lila saw was an old woman in her nightgown. The night before she was chasing her dog, Snowball, after a coyote went after it. Tonight, they find her walking down the road with a shotgun looking to kill the coyote. Nolan and Harper take the gun away, write her a citation and bring her back home.
