Until We Meet Again, My Angel

Chapter 1: Pages Burned

Dear Dean,

You still don't know I'm the one who saved you. It's been so hard to stay away. I know it was dangerous getting you out of Hell, I lost three of my brothers doing so, but I couldn't leave you there. You didn't deserve it. It was against Heaven's rules, saving you, and I will surely pay for that someday. But until then, I will do what I've been doing ever since I saved you two weeks ago- watching over you.
You know, I always thought it was silly the way humans believed in Guardian Angels. There aren't enough Angels in Heaven to cover all the people on Earth. But I will guard you. I won't let anything hurt you ever again. I've loved you for a long time, and I've been watching you even longer. It's true, Guardian Angels aren't real, nevertheless I was ordered to watch over you. I was told your destiny was long and complicated, but it must be protected. I'm not sure what they meant by that.
Still, I obeyed. I sat on my perch, and watched you as you slept. I followed you out of your burning house, sat next to you in your many high schools, and observed you from the backseat of your Impala, which you like to call Baby. I've gotten to know you very well, maybe even better than Sammy. I hope you don't mind me calling him Sammy, it seems only you can call him that. But, I digress.
I do know you very well. I now that your birthday is January 24th (1979), your favorite animal is a tiger, and you truly love hunting. I know you love pie, you take your coffee black, and you're allergic to cats. You're a skilled mechanic, and you love bacon cheeseburgers. You're terrified of planes, and, while you say you hate chick-flicks, you saw The Black Swan. You like repetition, which is why you always choose scissors in Rock, Paper, Scissors.
I also know that you resent your dad almost as much as Sam does. You're mad at him- for telling Sam not to come back, for never being proud of you, and for being less of a father than Bobby. But many people are worse fathers than Bobby. He is a good man, and I know you love him. I also know that you dream about your mother. I don't blame you. Mary was beautiful, kind, caring- the perfect mother. You dream about her holding you and Sam in her arms, singing "Hey Jude" and smiling at you. She misses you boys.
It was shortly after Henrikson sent you to jail that I fell in love with you. You were strong, you took everything in stride, and your smile never faltered. I always knew you were a good man, but that was the moment I realized you were perfect. I suddenly noticed what a pure green your eyes are, how lovely your smile is, and how resilient you are. Nothing can ever hold you down. I love that about you. Your will is strong- stronger than you think. But the most beautiful part about you is your soul. So bright, so strong, it's truly a miracle.
Sadly, I was informed there will be dire consequences should we ever meet. It is too dangerous to even send you this letter. I can't risk your life, you're too precious to me. I rescued you from Hell because I loved you too much to watch you burn, and that love with be the death of me, because it kills me to stay away. But I have to.

Until we meet,
Castiel

Castiel looked up from his paper to peer through the window of the cheap motel the Winchesters were staying in. He shook his head with a short chuckle as he watched Sam fall off of his bed. Dean laughed so hard, he fell off of his. Castiel loved to see him laugh- he never does it enough. Castiel stopped smiling as he looked back down at his paper. "Until we meet" he repeated to the empty air around him, and pulled out his lighter. A singe tear dropped onto the letter, as it slowly caught fire and burned away. Castiel vanished, reappearing right outside of the window. He smiled sadly.

Almost crying with laughter, Dean finally hoisted himself back onto his bed. Out of the corner of his eye, he thought he saw a figure outside the window. He turned his head, but no one was there. It must have been a car passing by.
