'Supernatural' Season 12 Spoilers: Castiel Returns, Helps Winchesters Deal With Lucifer's Baby

In the next episode of “Supernatural” Season 12, Sam (Jared Padalecki) and Dean (Jensen Ackles) will intensify their efforts in finding Kelly Kline (Courtney Ford). Thanks to the impending return of a familiar character, however, they will have some help in figuring things out.

The spoilers for “Supernatural” Season 12 Episode 19 tease that Sam has a plan to keep Lucifer’s (Mark Pellegrino) unborn child from wreaking havoc. But, the returning Castiel (Misha Collins) might interfere with the Winchester brothers’ plans reports TV Guide. It seems that the angel warrior may have a different way to handle the threat of the baby’s birth.

Kelly will have a hard time carrying the baby to full term. In the upcoming “Supernatural” Season 12 episode titled, “The Future,” she will be making a decision that may spell the difference for the baby’s fate. In the promo for the episode, a heavily pregnant Kelly is shown being held captive by Dagon (Ali Ahn). With less than a month before giving birth to Satan’s spawn, time is running out for Cas and the Winchesters.

Cas, Dean and Sam will try their best to put Dagon down but it will be very difficult. The powerful Colt does not work on Lucifer. Cas will even be almost killed by the Prince of Hell. Also in the “Supernatural” Season 12 episode, Dean is surprised that someone stole the Colt from them according to Carter Matt.

The British Men of Letters might have found a way to get the weapon from the Winchester brothers. It could be recalled that Mr. Ketch (David Haydn-Jones) planted a listening device in the brothers’ house in a previous “Supernatural” Season 12 episode. It seems that Dean’s initial apprehensions of joining the organization are correct. It has recently been involved on some questionable activities including killing one of their own agents, Mick (Adam Fergus).

What do you think will Kelly’s important decision will be? Find out when “Supernatural” Season 12 Episode 19 airs on April 27 on The CW.
