Sam (Jared Padalecki) and Castiel (Misha Collins) get closer to Lucifer's (Mark Pellegrino) baby, but they will disagree on what to do next. Meanwhile, the Winchesters will face an entity that will be difficult to defeat.

On the next episode of "Supernatural" season 12, titled "The Future," the Winchesters, along with Castiel, finally find Kelly (Courtney Ford). However, it appears that Sam and Cas will not be on the same page in what to do with Lucifer's baby.

"Sam comes up with a way to stop Lucifer's baby but Castiel has something else in mind for Kelly. Dean (Jensen Ackles) is furious when he finds out someone stole the colt. Kelly makes a bold choice about the baby's future," the episode listing on The Futon Critic reads.

In the episode 19 promo, Kelly is being told that she will die once the baby is born, which might lead her to come up with a decision that also disagrees with Sam and Cas' plans. The promo also reveals that the Winchesters will face an enemy that will be difficult to take down.

However, it seems that Cas knows who or what this enemy is as he lets the Winchester brothers know that "She's difficult to kill," to which Dean reacts like it's the understatement of the year.

Meanwhile, the colt will be missing in episode 19. Previously on "Supernatural" season 12, Mr. Ketch (David Haydn-Jones) trespassed inside the bunker and looked for the colt to no success.

Could Mr. Ketch finally have the colt in his hands in episode 19? Will the Winchesters figure out that it was the British Men of Letters who took interest in acquiring the colt? Mr. Ketch's intentions are very suspicious since he started having intimate relations with Mary (Samantha Smith) and took her photo with the young Dean from the bunker.

"Supernatural" season 12 returns on Thursday, April 27, at 8 p.m. EDT on The CW.
