Legacy

Caitlin Adams is a 16 year old with a... complicated past. Her mother was a woman who liked sex, so it wasn't a surprise when she was pregnant at 15. When Caitlin was born her mother started being more responsible. 13 years later, she has another child. A son, Alex. Unfortunately, she dies during childbirth. The next day a man comes to take the children to their new home. Well, that's what Caitlin thought. In truth, it was a demon. The demon proceeds to take the children to a small cabin where he plans to Caitlin over to Azazel while planning to kill Alex. Before he can finish the act John Winchester appears, exorcising the demon. After sending the demon to hell John Winchester takes Caitlin and takes her to Bobby Singer, not revealing to her anything.

When John arrived he explained the situation to Bobby. Caitlin was a Winchester. She was Dean's daughter, something that John made clear that Dean didn't know and would never know. He told Bobby that he learned that the demons were hunting her and Bobby needed to keep her safe. Bobby agreed and John left.

In order to keep her safe from the attempts on her life Bobby taught Caitlin how to hunt, making her an excellent hunter. When Caitlin is 14 she's an excellent hunter. But she has one problem. Alex. Her little brother, who was now was always in danger. She hated that, causing her to make a decision. To keep the most important person to her safe, she has to send him away. Caitlin gives him a small necklace, which would hide him from all supernatural things. And she sent him away to live a safe life.

Now Caitlin is 16. She's mostly on the road, but she still visits Bobby every now and then. She is currently trying to get away from everything trying to kill her. Every year, she tries to visit her brother. She's about to visit him again. Little does she know this one visit is going to change everything.

What happens when she goes to Bobby for help and he gets two brothers to help her out?
