6 cases identified
Case 1
Rhada: Labor and vaginal delivery
Rhada labors and delivers vaginally at Grey Sloan.
- Episode shows
- Rhada labors and gives birth at Grey Sloan while Jo and Levi are working in OB. The episode notes do not document complications.
- Clinical takeaway
- The case is a brief labor-and-delivery thread.

Case 2
Tour bus patients: Brain-death testing and donor triage
Fourteen tour-bus crash patients are possible brain-death cases; nine are potential organ donors.
- Episode shows
- After a tour bus is blown off a cliff, fourteen patients are potentially brain dead and await confirmatory tests. Nine are potential organ donors. Amelia supervises the new interns as she runs the tests and sends them to inform families when brain death is con...
- Clinical takeaway
- The case shows the mass-casualty brain-death workflow that drives the episode's transplant story.

Case 3
Marina Milton: Brain injury with recovery signs
Marina is initially grouped with possible brain-death patients, but eye tracking shows brain activity and she later wakes up.
- Episode shows
- Marina is injured in the tour-bus crash and is initially among patients who might be brain dead. Amelia sees that Marina is tracking things with her eyes, tells Marina's mother they are waiting for brain swelling to come down, and Marina later wakes up.
- Clinical takeaway
- The case distinguishes severe brain injury from brain death.

Case 4
Liam Collins: Brain death and organ harvest
Liam is declared brain dead after the tour-bus crash, and his heart, liver, and kidney are transplanted into Sarah.
- Episode shows
- Liam is in the tour-bus accident and is declared brain dead. A communication mix-up nearly keeps his mother from saying goodbye, so she asks that the family doctor review the case and repeat confirmatory tests. After the tests are complete, Liam's heart, liver...
- Clinical takeaway
- The case is the named donor pathway for the episode's multi-organ transplant.

Case 5
Sarah Martinez: Heart, liver, and kidney transplant
Sarah has multiple organ failure and receives a heart, liver, and kidney from Liam.
- Episode shows
- Sarah is in multiple organ failure and needs a heart, liver, and kidney. After the tour-bus crash leaves Liam brain dead, his heart, liver, and kidney are transplanted into Sarah. After surgery, she wakes up and is stable.
- Clinical takeaway
- The case is a multi-organ transplant recipient pathway.

Case 6
Howard Jones: Heart failure and unusable donor heart
Howard is waiting for a heart transplant, but the available donor heart has hematomas and cannot be used.
- Episode shows
- Howard Jones is in the hospital with heart failure waiting for a heart transplant. He is told a heart has become available, but Maggie opens the donor chest and finds multiple hematomas, making the heart unsuitable for transplant. Howard is told he will remain...
- Clinical takeaway
- The case shows transplant disappointment after donor-organ inspection.

Episode Summary
Everything Has Changed reopens Grey Sloan's residency program through a transplant-heavy first day. Rhada delivers vaginally. A tour-bus crash leaves multiple patients undergoing brain-death testing, including Liam Collins, whose organs are eventually recovered. Marina Milton proves not to be brain dead when Amelia sees eye tracking and later wakes. Sarah Martinez receives Liam's heart, liver, and kidney for multiple organ failure. Howard Jones, waiting for a heart transplant, loses a donor opportunity when the heart has multiple hematomas.
Differential Diagnosis and Testing Logic
The episode's central diagnostic distinction is brain death versus severe brain injury. Marina's eye tracking changes the pathway from organ-donor preparation to observation and recovery. Liam's case moves forward only after confirmatory testing is repeated. Sarah's case is transplant logistics rather than diagnostic uncertainty because the episode does not state the cause of multi-organ failure. Howard's case turns on donor-organ suitability, not whether he has heart failure.
Medical Accuracy Review
The episode is strongest when it treats transplant as a chain of decisions rather than a single miracle. Brain-death confirmation, donor-organ suitability, recipient need, and family communication all affect outcome. The main compression is workflow: real care would involve more documentation, organ-procurement coordination, compatibility testing, immunosuppression planning, ICU monitoring, and bereavement support.
