Merry Christmas

You woke up in blood. You've done it before but this time is different. Demons are lined up outside your door and the only thing keeping them out is the salt line so you decide to call in help. Sam and Dean Winchester. They come to the rescue just in time but things get complicated when they insist on keeping you safe and you're scared they'll find out the real you. So you leave them in the middle of the night and their hunt for you begins. They find you and kidnap you. You have to convince them not to kill you which may be easier than you think because Sam likes you.
