The Mask I Have Outworn (слэш)

When the Trickster seems to have killed Dean for real in his grotesque version of Groundhog Day, Sam knows it to be a lie and offers the Trickster a deal of his own in exchange for his brother’s life. The Trickster had no idea that in the wake of the deal’s consummation, the one who learned a lesson from the trick would be himself.
Now, the Trickster finds himself faced with two choices: leave the Winchester brothers to their Fate, stay hidden from forces he’d been avoiding for centuries and survive the coming battle any way he can, or tell the Winchester brothers the truth of the prophecy into which they were born, expose secrets that could cost him his immortal life, and dare to rewrite Destiny… all for the sake of love.
