Crowley knocked on the door of a boutique in the town "Now, let me do the talking, halo."
"Fine. You better not be up to any funny business." Castiel was clearly not at all liking the idea of Crowley taking the diplomatic approach, but he did seem more familiar with this world then he was, so he had no choice but to go along.
"Don't worry. It'll be fine" Crowley had a smug little grin on his face at having the angel wrapped around his hoof
A white unicorn mare came and answered the door, her curled purple hair elegant and her blue eyes blinking "Oh. Why hello again, darling." she said, seeming to recognize Crowley
"Yes, hello again, Miss Rarity. Would you mind if my friend Halo and I ask you a few questions?"
"Not at all. Please come in." she opened her door and allowed them to come inside as they each sat on a chair and she laid on her luxurious sofa "So, what ever could I do for you?" she then noticed Castiel in his tan trenchcoat "Except maybe a new style for your friend here, that is."
Cas looked over his outfit and realized it wasn't exactly fitting in this new world.
"Maybe some other time. We're on a bit of a tight schedule here."
"Fair enough, darling. So what did you want to ask me?"
"Have you noticed any unusual happenings around um...Ponyville?"
"Well, I can't say I have, Halo. Though I'll be sure to let you know if I do. Anything else?"
"Have you seen any out-of-the-ordinary mares walking through Ponyville?"
"Well...honestly, Hellion, I can't say I have...but again, I'll be sure to let you two know if i do."
"I see. Well thank you for your time, Miss Rarity. Always a pleasure." Crowley and Rarity shook hooves as they smiled.
Rarity finally took the time to look over Halo's trenchcoat and tie with dread "Oh dear...perhaps um...while you're here, I could fix you two up some new clothes"
"We should really get going"
"Oh, but I insist, darling."
Halo rolled his eyes and gave in, clearly seeing there would be no way to worm out of this without revealing the true reason they were here. And so the two sat as their measurements were taken forcibly "I should have something ready sometime tomorrow. See you then"
The two nodded and left "I hope were not still here tomorrow. For Dean's sake at least..."
