Hi everyone.
1. This one is Sam/Gabriel. It is post S5 fic, and written before S6. Sam escaped from the cage and drove a black car, like impala. Sam wasn't sure for himself being human, cause he could kill demons with his mind. And when he did that, his eyes turned black. Sam kept hunting and saved people, but sometimes, he found that he's still in the cage. Lucifer laughed at him and said, he never had been out of there and all he saw was a hallucination. Sam kept saying this is dream and hunting life is real, but he wasn't sure of it. Then, Gabriel appeared in hunting reality and told him the truth.
Found : It's Truth Crashed To Earth (Will Rise Again) by andrea_deer2. This one is Dean/Castiel. It starts with a story. There's a haunted town, seeral hunters went there and died. And the scene changed into Dean and Castiel, in 2014 verse. They fought hard but there was no hope, so Dean happened to kill Castiel, for saving Cas from hopeless present. In the end, world is saved, and the ghost in the town was revealed as Dean. Chuck and Becky tried to talk him but Dean felt guilty so much. Eventually, they couldn't pursuaid him to go heaven. The town is still haunted, all hunters who went there died, and villagers left the town.
I'm pretty sure that I saw the first one from FFnet, but I can't find it anymore. Does anyone know these? Thanks in advance.
