Tombstone

Tombstone is the 6th episode of Season 13. It aired on November 16, 2017.

Summary
Castiel is reunited with Jack and together with Sam and Dean, they head to a sleepy old western town to investigate a murder. Dean gets to live out his boyhood fantasy when he comes face to face with a famous, gun-slinging outlaw.

Plot
Dean and an unknown man walk through a cemetery searching for someone when two hands appear from underground and pull down the unknown man as Dean is dismayed at having to travel underground.

Two days earlier, Dean and Sam are still shocked at seeing Castiel alive again as he confirms its really him and explains he annoyed an ancient cosmic entity so much that it sent him back. With that, he is embraced by the brothers who questioned if he was in Heaven but Castiel replies he was in The Empty and tells the surprised brothers that his experience there was like travelling through an endless void of nothing. He explains he was awoke from his slumber after hearing a voice say his name as he is asked if God had something to do with it but Castiel replies God doesn't have control there as voices his belief that the brothers had something to do with but they reply it wasn't them as they believed it was impossible. The brothers soon realized that Jack (Nephilim) had a role in it and go off to tell him about it.

Deputy Carl Phillips is on patrol and pulled over the truck of a culprit suspected of grave robbery and had dispatch run the license plate number. Noticing the passenger side door open, Carl investigated, but found no sign of anyone in the truck as he was informed that the truck was stolen. As Carl was spooked by all the noise around him in the dark, he was dragged under the truck.

At the bunker, Jack is on the computer just as the brothers show up and reveal the resurrected Castiel.
