At Castle, Beckman is briefing the gang about what Bond has learned: Fulcrum is protecting a man code-named Perseus. He's behind Fulcrum's efforts to construct an Intersect. Perseus is going to be at a Swiss Consulate party that night, which Casey and Sarah will be attending undercover while Bond and Chuck stay behind to do techy things. The two, vying for Sarah's attention, volunteer to go with, but Beckman doesn't have time for that crap. Fulcrum's still looking for both of them, so just stay behind and measure each other's nether bits, would you?

Morgan and Jeffster undertake "Phase 1" of Operation Repulsion, which involves the three of them working up a sweat while wearing disturbingly tiny white shorts. Anna wants to go look at the apartment, but Morgan turns her down in favor of playing tennis video games and promises there'll be more of this when they move in together. Jeff drives home the point by stripping off his jacket and revealing his fake-tanned and furry torso, and offers to play doubles with Anna. Understandably, she bolts.

Swiss party time! Casey and Sarah test out their surveillance equipment, and back at Castle Bond remarks she looks fantastic. Chuck reminds him to focus on the mission, then adds that Sarah does, indeed, look gorgeous. Bond fills Sarah in on who's who and who's "packing" at the party while Chuck fills Casey in on an approaching tray of tasty crab cakes. Casey, it turns out, gets hungry on missions, so this is actually helpful advice from Chuck. Bond helps Sarah navigate her way away from a handsy Italian, which makes even Chuck smile. Casey looks over towards some people at the "ice goose" sculpture, allowing Chuck to flash on a man standing there. He's Howard Busgang, a.k.a. Perseus, played by Robert Picardo. [The man who introduced Velcro to the Middle East? - Zach] Sarah: "Good job, Chuck." Chuck revels in the praise before asking Bond about those nine Fulcrum guys. Bond says it's not as hard as it sounds; "Always go for the knee." Chuck: "You mean sweep the leg?" I... think that's what they said, anyway. I was getting distracted by Bond's scruff.
