At the hospital, Kowambe's guys have Chuck in an exam chair when Kowambe walks in. Chuck says he wasn't the doctor he expected to see. Kowambe asks him why he took his tooth and, moreover, why did he take the wrong tooth. Chuck's all gleeful about not being crazy, until Kowambe tells him that as soon as he reveals where he got his information, he will die. He pulls out a needle with colored liquid in it and says it's a truth serum. He injects it into Chuck and says he'll be extremely forthcoming in about ten minutes. Chuck fakes like Doc is there and gets up and runs into the hangout room or whatever it is. He asks for help, but all the other patients just sit there like mental patients.

Kowambe comes out, and Chuck flashes on kung-fu. But the drug's affecting him, because he does all his kung-fu moves onto the air instead of the bad guys. Merlin comes in and tells them to let Chuck go or suffer the wrath of Merlin. Merlin orders the spies to attack, and they all get ready for a fight, but Kowambe's men shoot them all with tranq guns. Merlin's like, "Damn!" Chuck tells him it was a good idea, though. Kowambe tells Chuck this is over. No one's coming. Which is, of course, the cue for Sarah and Casey to bust in and save his ass. Chuck's lying on the ground the whole time, motionless. When Kowambe falls in front of him, Sarah runs over and tells Chuck she'll always come back for him. Merlin creeps it up by sliding into the frame and saying, "So will Merlin, Chuck. So will Merlin." Doc tells Casey it's a good thing they came. Well, duh.

Casey's place. General Redhead apologizes to Chuck, who was right about Kowambe, who was scheduled to sell his research on organ harvesting and other bad deeds to a Ring operative. Chuck thinks that's fantastic! Well, you know, except for the organ harvesting and stuff. Chuck asks if he has a clean bill of health. General Redhead thinks it seems that way, but she can't actually clear him. Cut to Chuck chatting with Doc again, this time with much more confidence. He asks Doc if he's cleared for duty, and Doc says he was right: His dreams were caused by the Intersect. He's cleared for duty. BUT, and it's a big one, the dreams are also proof of the stress the Intersect's putting on his brain, which he believes will continue, likely leading to serious mental deterioration. Chuck asks what that means, and Doc says it's a new science, so time will tell. He tells Chuck he should discuss this with his partner, Agent Walker, and Chuck thanks him.
