Warnings: Warnings: Spoilers for 11.23: Alpha and Omega, past wincest.
Summary: Alternate ending for 11.23. Dean carries out the plan to suicide-bomb Amara, saving the world in the process. Just before he does, he makes Cas promise to stay with Sam, to "look after him and make sure he doesn't do anything stupid." After Dean's sacrifice, Sam is consumed with grief, going mad with desperation to get Dean back or die trying. In a last ditch effort to save Sam and make good on his promise to Dean, Castiel wipes Sam's memories of his brother, leaving Sam a broken shell of a man who can barely remember what he had for breakfast. This story assumes the London Men of Letters storyline doesn't happen, God has died or disappeared, and there is no Mary Winchester returned from the dead.
A/N: I still can't believe this thing is done! All hail to satanic-prom-dress, the wonderful artist who picked my crazy prompt, in which I really needed to see Sam protesting Dean's sacrifice in the Season 11 Finale, then suffering when Dean does it anyway. Also, thank you for putting up with my need to make Castiel useful to the max! Thanks to the mods of the 2016 sastiel_bigbang for tolerating my whining and bitching (because I couldn't make this story do what I thought it would when I started it but all I got was understanding and forgiveness. Mwah!) And last but definitely not least, many heartfelt thanks to my amazing, awesome beta, onlythefireborn, who asked excellent questions and taught me many things that will improve my writing. I don't deserve you!
