Talk about a twist!

After a season filled with the hunt to cure Dean's (Jensen Ackles) Mark of Cain, it turns out that Dean and Sam (Jared Padalecki) didn't actually want to remove the Mark…not after they learned what it truly was. You see, when Dean summoned Death (Julian Richings) to have Death kill him, the powerful being dropped some major truth bombs on Dean about the Mark of Cain.

First: Dean can never die as long as the Mark is on his arm. Second: it wasn't just a curse…it's a lock and a key, created by God himself to keep The Darkness, the powerful, malevolent being that existed before God and the angels, locked away. Think along the lines of Buffy the Vampire Slayer's First Evil, and then think even scarier.

That was enough to convince Dean that he couldn't have the Mark removed, and he didn't want to condemn another person to his fate, so he took matters into his own hands and bargained with Death. If Death banished Dean somewhere far away where he wouldn't hurt anyone for the rest of eternity, then he would allow Death to claim Sam's life that he was promised seasons ago, since Dean knew that Sam would never stop looking to find and save his brother, putting the entire world at risk.

When Dean took up Death's reaper to take Sam's life, we actually thought the older Winchester was going to do it! But we should never underestimate that brotherly bond: Dean instead swung the reaper and killed Death himself!

What does this mean?! Is Dean now Death? Or is Death dead, meaning that no one dies now?! We have so many questions!

But for the time being, those questions are being put on hold. Since Sam and Dean didn't have enough time to contact Castiel (Misha Collins), Crowley (Mark Sheppard) and Rowena (Ruth Connell) to tell them to stop performing the spell to remove Dean's Mark, they finish it, and a bolt of lightening soars across the country and burns it off Dean's arm.
