Back in the hospital, Ellie says that the Iridium 5 isn't working. It's slowed down the poison, but that's it. So they bought more time, but still need to find a way to save Sarah. Chuck wonders WTH to do, and Mary says Volkoff was working on a project a few years back called "Lead Apron." Chuck: "Which is a way to protect against radioactive poisoning." Hartley says he must have known Iridium 5 was weak, so he developed Iridium 6. Chuck asks what the time frame is, and Ellie says "a day, maybe less."
The gang heads outside; Casey says he'll call in a favor for some guys who'd be happy to give them a ride to Volkoff's headquarters in Russia, because they love mixing it up with the Reds. But Decker and his guys come out then. Decker tells Chuck he might be the Intersect, but he's not bulletproof, and they all draw guns on him. Chuck flashes and takes a couple guys out, but two others shoot him with a taser. Casey and Mary just watch on horrified (and they're surrounded too).
Hospital. Morgan tells a sleeping Sarah hilarious stories about Chuck being a hero. He tells her the point of the story is that Chuck never gives up, which she already knows.
Chuck's in a holding cell, begging Decker to let him save Sarah, who's CIA just like Decker. He just wants to get the antidote. "One last mission, that's all I'm asking for." Decker fires Chuck instead, and says Operation Bartowski is done and the Buy More's for sale. Chuck wants to just be let go then. But Decker wants one more thing from him first, because it's CIA property. He pulls out glasses that he says are a suppression device, which should only hurt "a lot." A couple of CIA guys hold Chuck's eyes open while the anti-Intersect flashes it out of him.
Then Decker has a meeting with Casey, and tells him that he needs to convince Chuck and Mary to stand down since no one can know the true origin of Alexei Volkoff. Casey tells him he's onto him, because he knows Chuck won't bail out on Sarah. He thinks Casey will try to escape with Frost and Chuck, but it's a setup and Decker will kill them all and then make himself out to be the hero. Decker pulls a gun and says it's okay, because he's not afraid to be the bad guy. But Casey's not either, and he topples the table on Decker before he can pull the trigger. Casey locks himself behind bulletproof glass with all of Castle's guns. He calls Morgan and asks if the CIA guard is still at the hospital. He is, so Casey tells Morgan to take him out now and meet him at the apartment. Then he makes his way to the cell holding Chuck, Mary, and Hartley. Casey and Mary are going to stay here and be the magnet, drawing Decker's attention away from Chuck and Hartley, who will head to Russia. They tell Hartley that he'll need to act like his old self, and then they explain Volkoff: mean, dictatorial, manipulative, conniving... Hartley wonders why they didn't tell him he was such a monster, then he realizes, "My daughter? I made her into me? I made her into Volkoff."
