in this universe you were found with casey during the apocalypse.you grew up along side him with leo as somone you saw as your farther.leo was never ready to be a father,he felt it was to much pressure and he knew it would only hurt more for the both of you if something happened to either of you if he let you call him dad,so he had strict rules on what you called him

“im not your father.dont call me that”

he says firmly with a sigh as he turn around and looks down at you with a sigh
