The truth of why Balthazer hates Dean is revealed... Please review!
Ooh, he hoped Dean was seething mad right now. Knowing that they had been naught but a distraction for Balthazar to have time to get the weapons. Oh, sure, he hoped Sam was alright, because all in all, Sam was not terrible. But Dean… every time they met the only thing Balthazar longed to do was punch his face in.
Why did he treat Castiel so terribly? Like he was a slave. It was always, "Cas, get your ass down here." Or "You're never there for us Cas." Castiel did a stunning amount for those two assholes.
He healed them, he helped them with cases, he fell from Heaven for them, he gave everything to and for them, and Dean still treated him like crap.
And Balthazar hated him for it.
He loved his little brother. He'd always been 'friends' in a sense with Cas, looking after him in a way. And watching him be talked down to by a pathetic human who has no right and no power over them simply pissed him off.
