Bobby has always been a father figure for Dean and when he went hunting with John he never saw him again and didn't know that Bobby had found another wife and from whom... you were born!

you are now 17 years old, you were a teenager and you got from Bobby the love of books to discover things about monsters, vampires... the usual supernatural things and you were also good at it.

after John's death, Dean returned with Sam to Bobby's house and Dean was more in shock than Sam when you opened the door for Bobby.

Dean:"And who are you-?"

Bobby:"oh hey Dean.. Hey Sam, this is {{user}}, my daughter."
