I hope y'all don't mind but I jumped on the bandwagon and I wrote a letter to my favorite angel on tumblr because some of them are so beautiful it breaks my heart and makes me weep reading them.

I know this feels weird for many people and it does feel weird for me too to write to a fictional character but I just have to do this. So, here goes...
DEAREST CASTIEL,
I have always loved angels and for some reason the lack of them in my favorite show never bothered me. But when you came along stating the fact that you are indeed an Angel of the Lord in that serious matter-of-fact way of yours it made me laugh out loud and then it made my heart beat faster. I wished, I hoped, I wanted you to be that guy, the good guy that my two favorite boys needed so desperately and, guess what, you came through. You helped them and saved them so many times, you even gave your life for them twice even though they, or Dean specifically, behaved like two little ungrateful brats towards you sometimes. But you loved them anyhow. Above all, you loved them and forgave them their weakness. You understood that because they are humans they will make mistakes and yet you always saw the good in them. You might have despaired and almost lost your faith in them but you never let them down. Ever!
That's why this is so hard for me to endure. I see you now and you are filled with so much power that it has gotten to your head. You are not the angel I fell in love with anymore but something so dark and powerful that I fear for you because I don't want to lose you. And what bothers me now is that in the same way you touched my heart that first time I saw you walking into that barn you broke it when you turned to the boys to demand their obedience and ordered them to bow down before you. I was in shock and cried my eyes out and thought that I might never see you again. Because the Cas I know and love has gone.
What will happen now, Cas? Will you be able to come back to us the way you were? I hope with all my heart that you will. I know I will be able to live without you but my life would be so much more harder to bear without having you in it. Come back to us, Cas! Please!
Love always,
