7x17 born again identity au but when dean finds cas he’s depowered (like, he didn’t die when he went into the reservoir, but he wasn’t doing too hot either and now he’s pretty much human) and he can’t heal sam. and sam dies, hurting and terrified and unable to recognize dean. who then does his best to beat castiel to death
spice it up with some tfw unrequited love triangle. castiel tells dean that he loves him and it only makes dean want to bash his face in even more; he knows how sam felt about cas, his brother might’ve grown a little bit since the 8th grade but he hasn’t gotten much better at hiding his crushes. and now sam’s gone because cas broke him, and he’s done so because of dean, and all dean ever wanted was sam
