I am looking a long, multi-part, wincest AU in which Sam, Dean, and John all have spirit animals with which they merge. Dean merges with a young wolf, Sam with a cougar, and John with a bear. At one point in the fic, Dean is kidnapped and forced to fight supernatural creatures using his spirit animal's characteristics. Sam uses his psychic powers in the story. Both Bobby and Bela appear in the fic. I would appreciate any help finding this fic!
