In episode 3.12 Chuck vs the American Hero, Sarah is mad at Chuck for allegedly executing Perry the mole in cold blood in his quest to become a spy for the greater good. Chuck cannot tell her what really happened with Perry at the train tracks because it would implicate Casey as a murderer and would also implicate Sarah, a federal agent. Chuck thus tells Sarah things are not what they seem and asks her to believe him but, engulfed in pain and guilt from her own red test five years earlier, she doesn’t. The next day, Shaw goes on a suicide mission to avenge his wife’s death, which Sarah mistakes for a selfless act; Chuck saves Shaw for Sarah’s sake after locking her in the castle for her safety, declares his love for her, and asks her to run away with him, to which she objects she has commitments (she’s expected to fly to DC and join Shaw there).
As she’s packing in the next scene, Casey drops by and tells her the truth about what happened with the mole, prompting a shocked and wordless reaction by Sarah.
What thoughts, fully formed or not, are going through her head? We can guess the following in no particular order:
- He couldn’t tell me what happened for Casey’s sake.
- He was willing to lose me to protect Casey.
- He asked me to believe him and I didn’t.
- Casey followed Chuck to make sure he was ok.
- Casey is a civilian confessing to murder for his friend’s sake.
- Casey is taking a risk by confessing to murder to a federal agent in a relationship with an agent other than Chuck.
- Chuck saved Shaw for my sake even though I didn’t believe in him.
- I didn’t corrupt Chuck by encouraging him to become a spy.
- Chuck has managed to become a spy while retaining his innocence, redeeming me and my profession.
- Chuck is stil Chuck, my Chuck.
