When in Doubt (Supernatural fan fiction OCxDean Winchester)

You think getting kidnapped and attacked by a changeling is bad? Well, this eight year old girl lost her mother to the changeling that impersonated her, was nearly killed by the lead changeling, then was saved by a hunter. She meant to thank him, but he vanished before she could. Ever since then, she had been looking for him. She learned his name when she was twelve. John Winchester. She found out he had two sons, Sam and Dean Winchester when she was fourteen. She was the same age as Dean. She thought, "Why don't I find his sons and they can lead me to John?" Her luck sucks, by the way.
Oh, and her name? Lillian Collins. She's human enough... Right?
