Will treats a patient who was misdiagnosed by his physician back in Ohio, and tries to reconnect with Natalie by asking her opinion about the diagnosis. She resists bantering with him, keeping their interactions to the bare minimum. His day doesn't go much better on the professional front -- he is able to definitely make a diagnosis for his patient, but the man is upset about the cost incurred. He had switched to an insurance plan with less coverage to cover the cost of sending his son to Northwestern, and is now facing medical bills in the hundreds of thousands. He commiserates with Connor at Molly's, and is bought a drink by pediatric surgeon Maia Frisch.
Sarah's father pays Daniel a visit, pushing to be added to the transplant list as his condition becomes more dire. When Daniel points out that he can only make a recommendation, and only if Robert addresses the issues they've previously discussed, Haywood immediately turns to Sarah and makes a blunt and cruel confession about how he was trying to use her. They end up treating a young woman brought in by her father after he found her at her mother's house, restrained and dehydrated. The patient's relationship with her father seems very similar to Sarah's -- parents divorced, father lost touch, a recent reconciliation -- and she starts to identify with the case. When they figure out that the woman is dissociating to her six-year old self after her father's visits brought back memories of childhood abuse, Sarah is outraged and verbally attacks the father as he flees the hospital. Daniel takes her to task, pointing out that he is not the one she's angry with. Later, she questions how they can possibly treat the patient when she's in such a state, and Daniel's explanation is clearly a prescription for how Sarah should deal with her own situation.
