Joanna, the woman Violet met in the airport in "God Laughs," stumbles into the office. She's been beaten badly, but loses consciousness before being able to identify her attacker. Violet believes it must be her husband, David, who has hit her in the past.
The team learns that Joanna is pregnant as she's rushed to the hospital. David shows up claiming he had a wakeup call after Violet talked to this wife. He swears he didn't beat her. Violet doesn't believe it. Addison determines there's no fetal heartbeat. The baby is gone.
A hysterectomy would give Joanna the best chance for survival. Violet knows she wouldn't want that. Unfortunately, it's not her call. With Joanna in an unconscious state, David has the legal right to order the procedure done. Addison manages to save the patient without doing the hysterectomy. David is not happy about this. He wants Joanna transferred to a different hospital as soon as possible.
When Joanna wakes up, she tells Violet that David beat her when he found out she was pregnant. She doesn't want to go to the police. It's not because she's afraid. It's because she's furious. She wants David dead. Her exact words to Violet are "I'm gonna kill him."
