Lost Winchester

6 years ago Dean Winchester and White Blackfire have a child on November 14, 2000. The child's name was Avery Winchester, she looked very much like her father. She had her fathers eyes, hair color, and loved metallic music just like her father. In 2003 Dean had to leave both Avery and White cause he knew if he would stay any longer both of them would get into harms way. Dean never wanted to leave not even for a second, but both Sam and Bobby told him it would be the right thing to do to keep Avery and White safe.
A couple months after Dean leaves some of his enemies found out that Dean had a daughter, but one thing he didn't know about his daughter was that she had amazing powers. She could control elements, she had pitch black wings, heal, she was both werewolf and demon/angel, etc.
3 years later Dean and Avery cross paths, but not how any one would like to meet their lost daughter or unknown father. Will Dean become the loving father he was or leave the girl to fend for herself? (A remix I guess of Dean Winchester's supernatural daughter)
