I am looking for a story I read a while ago. It is a multi-chapter AU future fic that features Sam and Dean, who, as adults, separate after a huge argument and spend several years apart. Dean later has a child with Cassie, but he and Cassie are unhappy together. Dean has that young child with him as the story continues. Sam has taken on another name, Jesse?, and is hunting for the other children of the YED with Ash as his lover/partner. Sam and Ash take these kids back to the Roadhouse where they all form a sort of safe camp. Dean follows and he and Sam/Jesse rediscover their relationship. This is a favorite and I have lost it. Has anyone ever heard of this one? It is very long, very dark and truly awesome. Thanks!
