Chuck goes to Castle alone, and goes all CIA spy, in Casey's gear: black clothes, boots, bullet-proof vest and two guns, which he bangs together dramatically. As he's leaving, Casey snatches the Intersect schematics from him and tells him how cute he is in that outfit. Chuck wants his plans back, but Casey wants to know what they are first. Chuck tells him they're designs for the Intersect, not stolen from Roark but given to Chuck by Orion. Chuck thinks Orion wanted him to break in, but Casey wants him to take off his gear before he breaks his neck. Chuck grabs the plans and points a gun at Casey, who tells Chuck he's entering a world of pain. Chuck says he wants the Intersect out of his head, and asks if Casey's going to help him or not. Casey asks if that's a tranq gun. Chuck looks at it and says it is. Casey's insulted that Chuck doesn't have the common courtesy to threaten him with a real gun, and tells him to put the toy down. Chuck shoots Casey, who wobbles a bit, but heads toward Chuck. He shoots again. Same thing. And again. Same thing. But now he's at Chuck, and has taken the tranq gun away. So Chuck pulls a tranq dart off his bandolier and stabs Casey in the neck with it. Casey says he's going to kill Chuck when he wakes up and then passes out. Chuck runs off saying he's sorry.
Chuck sneaks in to Roark when someone leaves. He's totally conspicuously dressed in his spy gear in a brightly lit hall. He hears someone shouting and ducks inside a room. It's his dad, who's being dragged out screaming that he's not leaving the building until his son gets his job back, because Roark screwed him, but he won't get to screw his son, too. One of the guys (the Fulcrum one Chuck flashed on in the auditorium) calls someone on a radio and asks what to do with him. The other end of the radio says to bring him in and he'll deal with him in private. One of the guys punches Bakula, so Chuck looks at his tranq guns, leaves the room he's hiding in and shoots a bunch of times. [Dramatic! - Z] All five guys surrounding Bakula stand there, and then fall to the ground. Chuck tells his dad they have to go, and he'll explain later. For now, all he can say is that he's not who he thinks he is. The Mummy walks in with a gun pointed, saying it's good to see both of them again. Bakula tells Chuck not to worry, because he's not who Chuck thinks he is, either. The Mummy tells them to put their hands up. When Chuck's dad puts his up, we see that it's an Orion-style computerized arm. He punches some buttons and closes the sliding metal door right on The Mummy. While the Mummy is pinned, Bakula knocks The Mummy out. He asks Chuck if he's coming. Wide-eyed, Chuck follows, saying, "Oh my god. You're Orion." Bakula: "We should hurry."
