The squad flies to Rio de Janeiro to face off against their nemesis Augusto Gaez (Lou Diamond Phillips), but old grudges start to get in the way of the mission.

Chuck flashes on a piece of the bomb, discovering that Augusto Gaez, a terrorist-for-hire and the squad’s nemesis, is responsible.

The squad infiltrates Gaez’s party in Rio de Janeiro, with Chuck, John Casey, and Morgan providing support.

While Chuck reviews CIA files to investigate Zondra’s potential guilt, the squad is captured by Gaez’s men.

Sarah declines Gaez’s offer to join his organization, and when he prepares to kill her, she frees herself and demands to know the identity of the double agent.

Eric Goldman of IGN gave this episode a score of 8 out of 10, writing, "The opening sequence establishing the CAT Squad (Clandestine Attack Team, of course) was great – a lot of Charlie's Angels mixed with a voice over that was a bit more Hart to Hart, keeping in line that it was Morgan imagining this."

"[3] HitFix writer Alan Sepinwall wrote, "We seem to be falling into a pattern with these bifurcated 'Chuck' seasons, wherein the original 13 episode arc wraps up, and then we get some fun standalones for a bit.

Sepinwall concluded, "I'm sure the search into Sarah's past is going to turn into a big arc in and of itself, but for now I'm just happy to have some light, entertaining 'Chuck' episodes.
