BEFORE

You know how Dean had a younger brother, Sam, and that was it??

Well this shows what they would've been like with a younger sister, whom is just like her oldest brother.

Isabella's mother died the same way Mary Winchester did, her brothers and father saved her from the burning house, and raised her to be a hunter just like them.

When John goes missing, she goes with Dean to pick up older brother Sammy, or Sam, as he likes it.

Seasons 1-4

(PSA!! I do not own any supernatural character only Isabella and her mother!!)
