Summary:Dean has been the provider all his life. He’s looked after his little brother - and he’s done a damn good job of it! But now Sam is more than capable of looking after himself, and where does that leave Dean? One day, Dean finds himself swept out past the mer village, and past the hunting grounds, into a place that no mer ever goes. And maybe… just maybe there lies the answer.

A/N: this is my christmas gift for nyeh413peasants as part of the spn_j2_xmas exchange. Nyeh413peasants said they liked au’s, and mentioned mer!au’s. I totally meant to write a smutty octo/mer/mer threesome, but apparently all I could write was fluffy pre-wincestiel friendship, so hopefully you enjoy this.

a huge thank you to relucant for reading through and waving pompoms for me.
