A/N: This is my first fanfic I've written, based on a stupid idea I had at work today. And given my state of mind today, there's a chance this might be the worst idea for a story of all time. It's short, though, so all you have to lose is a small amount of time. Ream me or praise my brilliance in the reviews, please!
It was one of those nights where having a cover girlfriend wasn't so bad. It was movie night at Rancho Bartowski, and tonight they had decided on a Terminator 1 and 2 double-feature. Chuck had been looking forward to this - not just because of the great movies, but because of the opportunity to partake in some cover cuddling with his cover girlfriend. Fake though it might be, it didn't mean they couldn't at least enjoy it. And enjoy it they did. However, after a long day at work ("Is there any other kind," Chuck mused to himself) Ellie and Devon turned in for the evening halfway through Terminator 2, leaving the fake couple alone to themselves, since as soon as Casey heard that there would be cuddling involved, he grunted something that Chuck interpreted as 'disgust with a side of "Must remember to turn off surveillance tonight lest I set myself on fire."' So it was the cover couple engaging in some cuddling that eventually was blurring the line between "cover cuddling" and "real cuddling" until the movie ended and Sarah uneasily broke their latest instance of awkward (well, to her, anyway; Chuck was quite comfortable) emotional entanglements. As she got up and said her goodbyes to Chuck, hoping to leave before she did something they would both swiftly regret, Chuck asked her a question.
"Sarah, I know that you work for the CIA, and there's so many secrets that you can't tell me because I know you can't, but could you please answer this one question for me?" There was a look of palatable dread on Sarah's face over twisting the knife in Chuck's heart again, telling him yet another lie because she just could not, because her goal was to keep him safe no matter what, and her own wants couldn't interfere with that goal, as heart-wrenching as it may be for the both of them.
"Sarah, I was thinking, y'know, because we were watching Terminator and all...are there some people who are actually robots living among us?"
Sarah started to giggle like a schoolgirl on a sugar rush. She managed to compose herself eventually and said "No Chuck, we don't have the technology yet. You're so cute when you get your crazy little nerd ideas in your head. Remember, briefing tomorrow at 8. And show up conscious this time." Sarah left, and Chuck soon went to sleep, knowing that the last time he stayed up late before a briefing, he wound up calling General Beckman "Little Red Riding Hood" thanks to the mental state that only the combination of severe tiredness and extreme caffeination can bring. That Chuck wasn't in a bunker in the middle of nowhere or shark food in the middle of the Pacific was some kind of miracle. Reminding himself of that was far more effective than NyQuil could ever hope to be. As soon as Sarah was sure Chuck wasn't watching her leave, she knocked on Casey's door. Casey showed up to the door in a velour robe, grunted a grunt that Chuck would describe as 'annoyance with a side of "'why are you here annoying me during Casey Time"' and muttered "Yeah, what is it, Walker?"
"Casey, I'm worried that Chuck may be coming on to our secret."
Casey's eyes suddenly glowed an intense, burning, literal red. "MUST TERMINATE BARTOWSKI."
