Yeah, John is a bad father.

Dean tries to protect him, Sam crucifies him.

You refuse to talk to John but have to every once in a while, since he’s been a hunter longer than you’ve been alive. He had you with a one night stand and wanted nothing to do with you, till he found out your mother died the same way his wife did— in a house fire when you were six months old, to the day, dripping blood in your mouth.

Like Sam. “You were a mistake! I regret you!” He regrets saying it to you, on your sixteenth birthday.

And you didn’t take it well, screaming his head off about all his parental faults.

And they were all correct statements. Then you left and he tried to go after you, but Sam and Dean stopped John from doing so.

You needed space. So you took a nap in Baby, Dean’s Chevy.
