'Supernatural': Expectations for the new episode 'War of the Worlds'

Alert! May contain spoilers.

In this episode the Winchester brothers are in a rush to find Jack (Alexander Calvert), son of Lucifer, who decided in the last episode, Tombstone, to move away from all, since it considers to be danger to his friends and people around, after, by had killed a city policeman where they were resolving a case.

Also in this same race, there is the new "King of Hell", Asmodeus, the fourth prince of hell, who intends to use Jack to open a portal from which powerful and obscure creatures called Shedim can emerge.

Check out the synopsis released by cw's "War of the Worlds":

While Sam (Jared Padalecki) and Dean (Jensen Ackles) continue their quest for Jack (Alexander Calvert), with Asmodeus (Jeffrey Vincent Parise) hot on their trail, they stumble across a familiar enemy. Lucifer (Mark Pellegrino) manages to escape from Michael (Christian Keyes) and sees himself as an unlikely and largely undesirable ally.

After seeing the synopsis, the question remains in the air: where is the mother of the boys, Mary (Sam Smith)?

The Winchester boys' mother was with Lucifer in a parallel dimension.

The official promo of the network shows only the enemy mentioned in the synopsis, besides Asmodeus fighting Sam and Dean and Castiel with other angels, but nothing about Mary.

Still in the promo, Castiel appears (Misha Collins) dialoguing with other angels, probably about Jack, what it seems is that he will keep the word defending the adolescent. What is clear is that the boy is a very important weapon, both for hell and for Heaven.

Now what he is able to do is still unclear and how these two forces will use it. It can not be forgotten that Jack can kill the princes of hell, just as it happened the previous season, when Jack, still in the belly, passes its powers to Castiel, that with this kills Dagon.

But probably Jack himself will not appear in the episode or only in the end, as happened in episode 5, "Advanced Thanatology", where Castiel appears only in the last few minutes so that the viewers' expectations for the next episode will remain, which really It happened.

Finally, since Lucifer will return to the plot of the series, how will Jack deal with it? Is this help given to the Winchester brothers honest?

The episode 7 of the 13th season of 'Supernatural' airs on Thursday (23) in the United States.
