Supernatural: Season 13 (2017 - 2018)

Season 13 begins with Sam and Dean picking up the pieces after the loss of their mother, the demise of Crowley and the heartbreaking death of Castiel. Meanwhile, the birth of Jack leaves the brothers with differing opinions on how to deal with a Nephilim; and Mary, after being dragged into the breach, must learn to survive Lucifer and an apocalyptic world.

Sam and Dean begin to explore what Jack is capable of doing with his powers, but an unexpected visit from Donatello alerts the boys to the fact that Jack will need more protection than the Winchesters can provide. Meanwhile, there is a new Prince of Hell in town, Asmodeus, and with Lucifer out of the picture he sets his sights set on Jack.

Missouri's friend is murdered by a wraith with a taste for psychics, so she enlists the help of Dean and Jody to protect her granddaughter, Patience, who has no idea she shares her grandmother's trait and could be next on the wraith's hit list. Meanwhile, Sam continues to work with Jack on learning how to control his powers.

When multiple patients of grief counselor Mia Vallens turn up dead, Sam, Dean and Jack investigate the mystery surrounding the murders and, each inadvertently, are forced to deal with unresolved grief of their own.

Sam and Dean investigate a case involving the ghost of a demented doctor and get assistance from Billie. Meanwhile, Castiel finds his way back to the Winchesters.

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.

Sam and Dean encounter a familiar foe when they continue their search for Jack, with Asmodeus hot on their trail. Meanwhile, Lucifer escapes Michael's grasp and finds himself an unlikely and mostly willing ally.

Sam and Dean agree to steal a mysterious trunk belonging to a demon named Barthamus in exchange for a locater spell the Winchesters can use to track down Jack.

Jack, desperate to prove to Sam and Dean that he is good and that he can control his powers, enlists the help of a dreamcatcher named Kaia to help him find Mary Winchester and save her from the alternate universe. However, when plans go awry, the Winchester brothers are the ones who need saving.
