Rabbit gets an email from Marisa that guides him to a page about Post Traumatic Stress Disorder (PTSD). He reads the symptoms and something hits home for him, but then he gets called to pick up Dr. Joe from the fundraiser. Marisa presses Rabbit to tell Dr. Joe about how he is feeling. Rabbit claims he hasn't had any flashbacks, but Dr. Joe says that watching a friend die could lead to PTSD.
Nancy continues to keep Will stable and he reveals that he is renovating the house in the hopes of winning his wife back.

Glenn and Nancy are almost arms-deep in blood and tissue. Will starts to crash and Nancy has to act quickly to save him and suture his artery. Her suturing job is a success.
Outside the burned-down restaurant, Chen, a large Chinese man, calls the prostitutes to come with him. Boone convinces Kim to come to the hospital instead. Chen doesn't like this. Meanwhile, Glenn irritates Rabbit by trying to bond with him over their unfortunate events this morning -- puking and fainting. Rabbit denies this and tells Marisa to back off about trying to convince him of the whole PTSD thing.

Boone approaches Chen and confronts him, then kicks him out of the hospital. Kim decides to testify against her oppressors. Nancy talks to Dr. Joe about Will. Dr. Joe is upset with Nancy because it's obvious she has the talent to be a surgeon, but she won't go through with it.
Rabbit bribes Teddy to take him up in the helicopter even though there is a wind caution warning. They are in the air and Rabbit pushes Teddy to fly higher, but he won't. Marisa tries one last time to talk to Rabbit about his PTSD. She doesn't want to have a medic that is losing his mind. Rabbit is worried after he gets his past out, he won't be able to get anything back in.
After work Nancy agrees to have a drink with Glenn, to his pleasant surprise. Glenn is impressed with what Nancy did today and it comes out that he really likes her. Nancy starts to be receptive to Glenn until he asks her about why she's not a doctor. He completely strikes out when he tells Nancy that he is writing a book about being a street medic.
After everyone has gone home, Rabbit, in an effort to overcome his PTDS, throws away the shoes he wore during the infamous helicopter crash. It may be his first step in overcoming the nightmare from his past.
