How you meet:

You were the creature the Winchesters were trying to find. It was in a small town were you had attacked multiple people. Every person who had been attacked had an different story. The first said he was attacked by Dracula, the next was abducted by aliens and the next had been knocked on the head by Captain America's shield. In short, one strange story. Sam predicted it was an shape shifter while Dean... He had no idea. They had went to the library for some research.

That was the first time you had seen them. You were there reading a book. Harry Potter and the chamber of secrets. In front of you were your already read books. The Origins of Dracula, Alien and a Captain America comic book. You were an trickster. Not just any trickster, the Alfa of the tricksters.

Sam and Dean had you figured out quickly after seeing you at the library. They had followed you before they cornered you. But what you hadn't expected was their feathery friend to join them.

"What are you" Dean threatened, holding his silver dagger to your neck.

"(Y/n), nice to meet you but I have other plans" With a flick of your wrists both boys went flying into the wall.

"Demon" Sam grunted. You shook your head with a smirk.

"Trickster" The feathered angel walked towards you and tilled his head, eying you with his blue orbs.

"You are an Alfa" You winked at him.

"The one and only. Also a god know as Loki, at your service" With a mocking bow you disappeared before their eyes.

You decide he can stay:
It had been a while since you had seen the Winchester brothers or their angel, Castiel. Of course you asked a friend of yours who the angel was. You know Gabriel right? Fake trickster? Archangel? Well he was your friend and business partner. Inside your new home, a nice apparent in Brooklyn, you are the last bit of your chocolate cookie before falling onto the couch. Being an Alfa was hard work. Ordering tricksters around, creating mischief and eating candy, took a lot out of you.

Stretching, you leaned back and was about to turn on the tv when the sound of wings reached your ears.

"Hi Gabe" You greeted turning on your tv.

"Do you mind learning my little brother here about earth" Without waiting for an reply Gabriel clapped his hands. "Great, I owe you one" And he was gone. You groaned turning of your tv before turning to the Angel Gabriel had left. It was the same angel that had helped the Winchesters.

"I do not know what happened" Castiel tried making you smile.

"Looks like you got Loki'd" Castiel turned his head and was about to ask something when you cut him off. "Never mind. Welcome I guess" You turned back to the TV and turned it back on.

Your favorite quote of his:
"Bite me" the way he stood up to his fellow Angels. Still gives you the chills.

He realizes he likes you (Friendly way):
You take your time with him. He doesn't understand the simplest thing about humans so it will take a lot of time for him to understand. You give him that time because you have nothing better to do anyway.

He realizes he loves you:
He kept coming back to you. No matter how far or long he left he always came back. It bothered him at first before Balthazar told him he was in love all the way up to his feathery ass.

His favorite Disney movie:
Hercules. It had gods in it like heaven and Poseidon, Hades and Zeus remind him of the Archangels.

You take him to Comic Con:
"Why is that woman in her underwear?" Castiel asked seeing a slave Leia cosplayer walk past. You sighed and tugged him with you. You had tried to get him to cosplay but he was impossible so you just cosplayed yourself and made him carry your bags. Your cosplay? Loki the God of mischief and lies.

You break up:
You had started helping the Winchesters after Gabriel 'died'. You had lost some of your childish ways after it and needed something to keep you down to earth. The Winchesters offered to help you. Not like they had a choice in that manner. It was either that or you going back to you're tricking sprees. Sam had actually taking a liking of you seeing you were vaguely interested in technology and knew a lot of lore, because you had been there of course. Cas's visits became less and less before he didn't return at all. Having bigger problems to worry about you tried to forget about the blue eyed angel but soon you couldn't anymore.

The brothers had gone out for a food supply run, leaving you alone in the hotel room. You sighed and sat down on the bed. You closed your eyes and folded your hands. Can't believe I'm doing this...

"Castiel, if you can hear me. Know that I have been going trough a hard time and I would have appreciated your company" you opened one eye to see if the Angel had appeared. No luck. "But it seems like you have more important things to do than being here. We're done Cas.  If you have an objection you can gladly come here to talk to me" you unfolded your hands and stood up. What a dumbass.

How he handles the break up:
He tried to ignore the strange feeling inside his chest when he heard your prayer. He knew how hard it was for you to pray seeing a god should not pray. And he felt very guilty and confused.

Halloween costumes:

Angel and Devil. You gave Castiel fake angel wings and an halo but let him keep his trench coat. Cas couldn't understand why you had horns and a tail but understood that it was an mortal tradition.
