Agent Dash

Rainbow Dash POV...
My assignment was to break into Rarity's house, and scan for any evidence of her being the mole. Or possible betrayal, whichever one I find. If I find neither, I can go back and tell Celestia I was right, that Rarity is too frou frou to ever hurt a fly. But if I'm wrong, I can stick my hoof in my mouth and deal with the consequences just like the adult pegasus I am. I can also monitor her immensely and record her every move. Fun. Just like Celestia said it would be. I start in her boutique, silently slapping on some gloves that are thick enough to cover my hoove prints. As soon as the drawers open. Squeaking as loudly as drawers ever could, I silently berate them, and open them slower, hoping to minimize the annoying and possibly career ending noise. I don't know why it matters to look in her boutique, she's Rarity for pony's sake, it's not like she's secretly a sniper! I continue to scan all the drawers, and find nothing. I wish I could just go home, but I remember my promise to Celestia to do this. It's not like she had mentioned any of this in the beginning...
Flashback to when Rainbow was recruited-------------
"Rainbow Dash, I am grateful for your help.", a voice from behind her sounded.

As she turned around, she saw it was Celestia and broke into an incredibly low bow.

"However, I am afraid I have much more to ask of you. It would ask a lot of you. Pinkie is too loud. Twilight is too physically inadept, Rarity is too much of a showy pony, Applejack is too honest. And Fluttershy is much too meek."

Rainbow Dash raised an eyebrow, intrigued by what the princess was saying.

"Rainbow Dash, would you like to serve your land further than being in the Elements?"

"What do you mean?", Rainbow asked raising her eyebrow again.

"I mean putting your life on the line for Equestria. Risking it all to defend this land, and protecting the ponies you love."

Rainbow immediately thought of Fluttershy when she heard the last sentence.

"Of course it would take training. Lots of work would have to be put into protecting the Elements of Harmony. And you would have to swallow your pride along the way in order to do the job I'm offering you. Rainbow Dash, have you heard of H.A.R.M.O.N.Y?"

"What? Yes I know what harmony is!"

"No, the organization."

Rainbow raised both eyebrows.

Celestia, the goddess of the sun, groaned. Loudly, and then she started to pace. "I knew I never should have done this," she mumbled, "now you are probably scared, are you not?"

Rainbow shook her head. And then she sighed. "Princess, please tell me what's going on! Tell me what Harmony is!"

Celestia stopped pacing. "Fine," she said sternly, "but you don't know what you're getting yourself into if I tell you."

"I know," Rainbow answered, her curiosity guiding her head and heart.

"H.A.R.M.O.N.Y is an organization. An organization I created to help guide this world away from evil and destruction. It's the organization that battles chaos."

"C.H.A.O.S?", Rainbow asked, clearly knowledgeable on the subject.

"Yes, do you know about it?", Celestia asked, her interest now piqued, wanting to see how much the cyan pegasus knew about the organization."

"Know about it?! Of course I know about it!", Rainbow said exploding. "They're only the most dangerous terrorist organization to all pony kind! They are honestly something that needs to be stopped!"

Celestia sighed, at least she knew which side Rainbow was on.

"H.A.R.M.O.N.Y is the organization that battles C.H.A.O.S.", Celestia calmly remarked, and watched as Rainbow's face erupted into a smile. "But like I was saying before," Celestia continued, "I believe that you could serve your land further than being in the Elements. Rainbow Dash, H.A.R.M.O.N.Y is an organization for spies."

Dash squealed. "Are you asking me to be one of your spies!"

"Yes," Celestia said, and instantly berated herself for not going up to Rainbow Dash and telling her right off the bat.

"Wait, hold on, do I have to spy on my friends?," Dash said, losing some of her enthusiasm.

"Yes," Celestia said, disappointedly, getting ready for Dash to say no. "There could be a potential agent of Chaos in the Elements of Harmony, and we're looking for somone to keep an eye on things."

"I know, because Twilight's just sort of a borderline control freak who doesn't have the greatest stamina, and AJ is to honest to keep the secret, and Pinkie is too emotionally unstable, I get it.", Rainbow said.

"I know this is asking a lot of you, Rainbow Dash, but by the loyalty in your heart I figured you would be the perfect pegasus for the job.", Celestia said. "And I see no other option."

"Wait," Dash reiterated, "you want me to spy on my friends to possibly save Equestria, and join an organization filled with ponies to stop a crazy terrorist organization that could easily rip my mane off." Dash rubbed her mane. "I kind of like my mane. But I'm nothing if not loyal, so I'm going to stay loyal to harmony, princess."

Celestia's protection plan was finally falling into place. Keeping her tone, and expression, and body language neutral and serious, she managed out a shaky, "do you promise to serve your country?"

"Yes," Rainbow Dash said, taking Celestia's hoof as they shook on it.
Flashback end--------------------------------------------------------
Yes, Celestia had never mentioned anything about snooping through Rarity's stuff. She was her friend, and besides, the prissy unicorn had probably never gotten her hooves dirty in her life, aside from the occasional sisterly social, and unfortunate prank accident. Caused by her and Pinkie, of course.
Rainbow POV, again....
'I may be a spy, but I'm not faking my relationship with any of these ponies. I love them all.', yet here I am, rooting through Rarity's drawer. Checking to see if the coast is clear, I tiphoof upstairs.
