Morning at Castle. Camera trickery takes us from a street, through a grate, down into Castle. Agent Superman presents Sarah with a coffee, which he tells her is a "double shot Americano, no cream, no sugar. Just the way you like it." Then he adds a stirrer, saying he noticed she likes to chew them when she gets nervous. Casey and Chuck come in and greet them as Sarah throws out the stirrer Agent Superman gave her. Then Agent Superman explains what's going on: The CIA is not interested in stealing the Mask of Alexander, but they believe the artifact and others are being used to smuggle items of interest to the Ring through customs. He shows them surveillance of a team breaking into something in Damascus, but not taking anything. Casey thinks it's pretty smart, since artifacts wouldn't have to go through security (that cannot be true). The plan: Chuck will be in the control room, Casey will handle surveillance, and Agent Superman and Sarah will pose as guests, then break in and swap the mask with a replica. Sarah asks about bringing a civilian on the mission, and Casey suggests some tranq darts he'd like to try out, but Chuck says he can handle Hannah. Then he adds, jokingly, "Besides, she can cover for me in my Nerd Herd duties in case you guys need to call in the big guns." No one gets that it's a joke, so they all just stay silent. Chuck: "That would be me. When I say big guns, I'm referring to the Intersect, myself. Do I need to flash? Glad we had this talk." Hee.
