Sam and Dean are two brothers that live for the hunt, but one day they decide to go on a little fishing trip, for shits and giggles. Little did they know, this would end up changing Dean's life forever. Castiel is a mystical beauty; that lives in the deep blue water underneath Sam and Dean's boat. He's quite lonely, and doesn't bother anyone. Castiel has been alone for Eons, eventually meeting humans here and there every few centuries. The humans have spread rumours of Castiel, the mean looking merman who lives in the lake, but as I've said before.. Rumours.
