If I Were To Fall (Supernatural)

"Please, brother. I need your help. I need you to trust me. The others are coming after me. I disobeyed. I told them I wanted to be free. I need protection; I can't take them all on alone, nor do I have the strength to."

Sariel is an angel. She's a powerful one at that. She loves her brothers and sisters. Sariel is a free thinker, like Lucifer, but obedient, like Michael. She's in trouble now; she disobeyed. It's chaos in heaven with the apocalypse looming over them all. Sariel has nowhere to turn and won't-- can't --choose a side to be on. Now, chased out of Heaven by her own brothers and sisters, she turns to her only brother she knows will understand: Castiel. The only problem is that last time she saw Castiel they had a slight falling out. He's now on earth with the Winchesters attempting to prevent the on-coming apocalypse. Will Castiel help her? Will she help Castiel? But the question is: can she even be saved? Is this really what God has planned for her?
