Inside the room, Chuck immediately flashes on the guy standing by the bed and the guy in the bed. He sees lots of deserts and explosions in both flashes. Chuck tells Agent Cylon it's him, and the guy next to the bed asks if Chuck's his doctor. Chuck says he is, adding "Am I not wearing a doctor's coat?" Cute. The guy by the bed says he's Harry Lime's private physician, Dr. Mohammed Zamir. They "Doctor" each other a lot -- meaning they greet each other as doctor. And then they send Agent Cylon and the other nurses away, each saying doctor about 700 times. [Shades of Spies Like Us? - Z] Outside the room, Agent Cylon tells Casey that the ID was affirmative, so he should proceed. Casey slides his key card, but a nurse calls him back to clean up after someone who didn't make it to the toilet. Casey goes to help.

Chuck uses his stethoscope on the patient, and then says his heart sounds normal for someone with this condition. Zamir tells him how special this patient is, and Chuck explains that he took an oath to treat all patients with the same kind of care. Zamir says it's a dangerous job to be a surgeon of a very important man. Chuck says he'll do the best job he can, and Zamir says his life depends on it.

In the hall, Chuck jokes to Agent Cylon that if he has to eat an apple a day to keep that doctor away, then bring on the fresh fruit. Okay, first, I don't think Zamir's a real doctor. Second, not a very funny joke, Chuck. Agent Cylon just looks at him and he acts disappointed. Okay, so Sarah would have pretended that was funny, but it would not have been easy, because it wasn't. Casey comes up and tells them he can't get in to the room with the pacemaker, so Agent Cylon says he'll have to steal a doctor's key card. Casey tells her he likes "the cut of her jib." Chuck tells them they're a match made in some very frightening part of heaven. Just then Casey sees Awesome, and Chuck realizes they want to steal Awesome's key card. Chuck says, "Not Awesome." Or maybe "Not awesome." I think he means both.

Back at Castle, Chuck's telling Agent Cylon, Sarah and Casey that he's not getting his soon-to-be brother-in-law involved in a spy mission. Agent Cylon says Chuck doesn't get a vote, but Sarah wonders if there's a different doctor they could access, since this mission puts Chuck's cover awfully close to the action. Chuck agrees, saying this proves he and Sarah are connected professionally. Sarah smiles cutely. Casey says not that many doctors have the specific key card, but Ellie's Ken Doll is one of them. Chuck asks how they'll get it, since you can't just walk up to Awesome and ask for it. Agent Cylon gets out her tranq gun, but Chuck says no. He thinks he knows a way they can have their spy cake and eat it too.
