Belle French knew that looks could be deceiving. Sitting across from Gaston Gustav people would simply think they were just two young kids on a date. Then again that's exactly what she wanted people to believe. If anyone was to truly suspect that little Belle French was actually an espionage agent for the CIA and was working to gather information on a communist organization located right in her home town of Storybrooke she'd be in deep trouble. She had worked for the CIA now for three years but had spent the last two and half years in rigorous training with no field experience. It was only six months ago that she graduated from training courses and gained the title of an espionage agent. A few days afterwards she was given her first assignment. Which is how she found herself in a small diner with the most boring guy she had ever met listening to yet another one of his hunting tales.

"It was easily a ten point buck, it was huge! I had waited there all morning and the dumb beast just walked right past me. Boom! One shot and it dropped. I bagged two more after that, a seven and eight pointer a piece. It was quite the day Belle! You would have loved being there.

"Oh I so would have!" Belle was glad that Gaston was as dim as he appeared and couldn't hear the lie behind her words. Instead he beamed at her, obviously taken in with her duplicity. She gave a small smile in return before stabbing at the plain salad Gaston had ordered for her. Next to his steak and mashed potatoes, both smothered in a thick gravy, her salad, even covered with light dressing, looked absolutely ridiculous.

Six months of pursuing and "dating" Gaston had meant grapefruits, without sugar, for breakfast, salads, sometimes with dressing, for lunch, and if she was lucky he'd order her fish and brown rice for dinner. If it wasn't for her weekend away when she "visited her father" she'd have lost close to 20 pounds in the last six months. Of all the little annoyances that came with this assignment, the tiny apartment, the lunk of a boyfriend, enduring nights spent together in his bed, his pillow talk consisting of communist propaganda, the diet he forced her on so she would "stay trim" was the absolute worse.

"So how was work Baby? You've spent so much time at the office lately it feels like I never see you anymore." In truth the less time she spent with Gaston the happier she was but her cover required her to play the part of the devoted girlfriend. With that meant pretending to be upset when she didn't see him. Pouting, laying on the guilt and using the dreaded "puppy dog eyes" when all else failed to keep up the act. Part of her almost felt bad about using the guileless Gaston, guilt being the one thing the academy hadn't been able to completely train out of her, but then she would remind herself that he was working for the Soviet Union. He was a traitor to their country, he was guilty of treason, and for that he didn't deserve her guilt.

"Belle babe, you know I'm working on a big project and the boys can't do nothing without me."

"That was a laugh. Belle knew that Gaston was a member of the Cora Mills' Soviet organization, but he was the low man on the totem pole. The only job he was trusted with was scoping out new people for the cause. That's why she was chosen to approach him. The petite little blue-eyed beauty was the last person someone would expect to double cross them. It was her job to fluff up his ego and get him to talk about what the organization's plans were, or better yet get him to invite her in.

"I know you're busy but I miss you Baby. I just want to spend time with you." Cue the pout.

"Well...maybe this week you can come visit me at work. Bring me my lunch or something."

Bingo.

"Really?! Oh Gaston that would be great!" Reach over the small table Belle threw her arms around Gaston's thick neck and pressed a kiss to his stubbly cheek. This was exactly what she needed, a way in. If she could into Cora Mill's headquarters she'd be gold.

I hope you enjoyed it! New chapters should be posted every few days.
