The ambulance arrives, swerving all over the place and the two EMT's stumble out both laughing uncontrollably. Patrick opens the back of the ambulance to find the patient also in an uncontrollable fit of laughter, and determines nitrous oxide is leaking. He jumps at the guy dressed in camo as he moves to light his cigarette but it's too late, there is an explosion. Patrick is thrown to the cement, the other man is thrown into some combat flashback, and it is Jason who must pull the patient, who is on fire, from the ambulance and put out the flames with his jacket.

With one of the attending physicians now a patient, it would seem the remainder of the episode is spent introducing viewers to the new doctors and nurses, and following through with the medical stories which were set up. It turns out the man in camouflage is a post-traumatic stress patient who has served two tours in Iraq. He has little interest in consoling with Lainey though, he just wants her to prescribe him some Percodan and send him on his way, saying she can't fix what's wrong with him. Near episode's end he is able to steal some during an intense moment.

We find out the pregnant woman who was knocked off her feet by the explosion, is HIV positive when Robin is sent in to bandage her scraped knees because Dr. Lee had an emergency cesarean to perform. In this segment as well as follow ups with Robin and Patrick, and then later Jason, we once again see Robin struggling with her inner desire to become a mother someday, despite her HIV positive status. What's not familiar, however, is Patrick being even just a little bit open to it.

While Jason is waiting for Spinelli to receive treatment, he learns the woman he pulled from the ambulance died. For much of the remaining episode, the student nurses are trying to find out her identity from the hotel she was staying in. All we as viewers learn is the last name – Barrett – the same as Cooper's last name. Coincidence? I don't think so. Especially since rumors have been flying that the role of Brenda Barrett is being recast so the character can return to the daytime drama.

When student nurse Regina finally obtained the mystery woman's identity and took it down to the morgue, she discovers the woman is not dead when she moans and raises her arm. As the closing credits and montage began rolling, we see the gurney surrounded by hospital staff, including the new cardiologist Dr. Julian and a very stunned Nurse Regina wheeling her back into a trauma room and working on her. I look for this story to arc to be one of the few to cross back to the daytime counterpart eventually.
