A Mother’s Return and a Painful Past
The episode, written by Jen Klein and directed by Alexis Ostrander, centers on Sharon Leone’s personal life being upended. Her long-lost mother, Ruby, played by Oscar-winning actress Christine Lahti, appears without warning.
This visit is not a happy reunion. Ruby’s arrival stirs up painful family history that Sharon has long tried to avoid. The storyline follows from the recent revelation that Sharon’s late husband, Vince, had been secretly sending money to Ruby to keep her away from the family. He believed that Ruby could “push all her buttons” and unravel Sharon during a difficult time. In a recent episode, Sharon left a voicemail for her mother, telling her about Vince’s death and firmly asking her to continue staying away. Ruby’s decision to ignore that request and show up at Sharon’s door sets the stage for intense drama.
“Oh, honey, I got your voicemail,” Ruby says as she arrives. “Vince died? It’s going to be OK now, momma’s here.”
First-look images from the episode show Sharon and Ruby in a serious conversation inside Smokey’s Tavern, with both women appearing tense.
