*DON'T HAVE TO WATCH THE SHOW TO READ THIS! IT'S AU* Sarah Walker is the CIA's best. She's Director Langston Graham's wildcard enforcer and she's been with the agency since she was a teenager. After years of service, she is partnered up with Agent Charles 'Chuck' Bartowski, a guy who is sweet and nerdy but has only been with the agency for a few years. As she spends more time with Chuck, she feels herself getting softer and opening up to him about parts of her difficult past. She didn't expect to fall for him though since the first rule of being spy is to never fall in love...

Colonel John Casey has spent the last 4 years going on missions and protecting special government interests with Agents Chuck Bartowski and Sarah Walker. He's a man who is born and bred for secret missions and assassination-type directives, leading always with his head and never letting his heart get in the way of getting the job done. When a foiled assassination attempt lands Amelia Cershaw in the sole protection of Colonel Casey, he finds himself on a mission that even he finds difficult to do--- DON'T FALL IN LOVE. *I do not own any of the main characters or the settings (including places or items dedicated to) of the TV show "Chuck"
