Hi. I am looking for a fic I read a while back. It was a post apocalyptic fic where Sam said yes. Dean found him after they defeated Lucifer with his fellow freedom fighters. He thought that Sam was dead. Sam was wearing the white suit from endverse. Sam twitched or something so Dean knew he was alive. the other fighters wanted to kill him but Dean couldn't do it. He took Sam away and they were living on the outskirts of a small town. Sam was catatonic. He could move, he could wipe his butt and eat if you put food in front of him but he didn't talk. Then one day he just started talking but he'd lost all his memory. Didn't know who he was or Dean. He found a journal and read it and pretended that he'd regained his memory because he saw that Dean really wanted 'his' Sam back. I can't remember the name of the fic, or who wrote it. I've searched the post-apocalyptic tag on AO3 but haven't' found it. Does anyone know it's name or the name of the author?
