But Awesome's not willing to leave and save himself and leave his patient, so he tells them to go, but this is his mission. The premier's guards come in and want to kill Casey, but Chuck wants to save everyone -- Casey and the premier. The guy says if Chuck wishes to prove he's not an assassin, he should prove he's a doctor and save Casey. Casey and Sarah sit down to "operate," and Chuck gets nervous and hot. Finally, right before a guard shoots him, Awesome talks Chuck through it (while keeping the premier alive), saying he has the hands of a surgeon and can do this. Chuck flashes and then asks Sarah for: suction, scalpel, tweezers, gauze, iodine, forceps. He says, "Just like Operation... you know, the game." Then pulls the bullet out of Casey's leg. Sarah and Awesome are so proud. The premier's machines start beeping, and Awesome says he tried to tell them there was nothing he could do for him here, without a blood transfusion, and he doesn't even know the premier's blood type. Casey knows it's AB-negative. He says, "You learn a lot about a guy when you're trying to kill him." He also knows his favorite movie is Terms of Endearment and always showers after lovemaking. Awesome says that's not going to save him, and they need someone else with AB-negative. He asks in English and Spanish, but no one speaks up, so when Chuck notices Casey's shifty eyes, he checks Casey's dog tag. It says "AB-negative," of course. Casey's not having it, so Chuck gives him anesthesia.

Casey comes to in Castle and says he feels like death. He asks what happened. General Redhead pops on the screen and congratulations them, though she doesn't endorse their methods. She thanks Casey for his extraordinary sacrifice. All he remembers its getting shot, but then it comes to him. He looks at Chuck: "You stole my blood and you put it in a stinking Commie despot." Chuck says "former." They present Casey with a thank-you gift from the premier. It's cigars and a card that thanks him and calls him "the Angel of Life."

Orange Orange. Awesome shows up and asks how things went. Chuck says there's no new mission for Awesome, who says he scratched his espionage itch. He says it was all killer, but it's not worth it if you have to give up half your real life. Sarah comes in and Awesome says he has to run to the hospital, finish up some stuff, and get home to his wife. Sarah tells Chuck that Awesome would have made an awesome spy. Of course. He's awesome at everything. Chuck tells her it runs in the family, and she smiles. He asks her what she thinks their cover should be moving forward, and she suggests keeping it simple: friends. He thinks that could work, that he could fake being friends with her. She agrees she doesn't find him completely repulsive. It's a deal. They even shake on it. She asks what friends do, and he says he and Morgan would gorge themselves on processed food and play video games. She says they're not quite there yet, so he suggests they come up with other options.
