Lea flips through channels looking sad. Her phone rings. It's her mom. She declines the call.
The plan is to use catheters to install a new valve. Shaun shows up out of nowhere and says this will kill him because Artie has cold feet, which he thinks is caused by a damaged vessel. He and the other doctor get into it and Shaun inadvertently insults the other doctor and keeps insisting this procedure will kill the patient.
Shaun undermines everything by going to Mr. Hill himself, which irks Andrews to the point that he tells Shaun that he is not thinking straight and should go home. Shaun still refuses. He leaves and the other doctor tells Andrews he would have fired him.
