With the help of Castiel and Meg, Sam and Dean will stop the leader of Leviathans from executing his plans, but Crowley warns the brothers that Dick knows what they're after.
Sam and Dean are having their one stake at killing Dick Roman in "Supernatural" next week. The Winchesters prepare for the big battle as the leader of Leviathans is in the final phase of his plan.
To stop Dick, the Winchesters must team up with Castiel, Bobby, Meg and the young prophet Kevin. However, Dick is one of the smartest enemies they've ever faced so it's a mind game to see who can keep the upper hand.
"Dick's not an idiot. He knows what you two are after," so Crowley warns the two brothers. Meanwhile, Dean's last message for Sam before they embark on the risky mission is "don't get killed."
Titled "Survival of the fittest", the season 7 finale of "Supernatural" will air Friday, May 18 at 9/8c on The CW. Misha Collins, Jim Beaver, Rachel Miner and Osric Chau guest star in the episode.
