Saving the Winchesters

You are a very shy hunter of the supernatural. You stay away from other hunters because you don't trust them and you work better alone. When you meet the Winchester's and the angel that accompanies them, things change. You start falling for Castiel, and the Winchester's become like brothers to you. You never thought you would be capable of trusting other hunters and an angel, when you can barely trust yourself. When something happens to Castiel, you did the only thing you could for him. But the angels start to question their trust for you. Should you risk your life to save Castiel?
