User blog:KillRoy231/Mary and Lucifer to return

Well, I think we know who the main villain of Season 13 is.

Glorifying the devil to make him the villain of three seasons (breaking the record of two set by Azazel and matched by Lilith and Crowley), and officially appear in four.

Besides, Crowley is confirmed Killed Off For Real even though Castiel will be revived.

Lucifer is popular, and now we know Supernatural is killing main villains again, and no longer has any restrictions on fan-favorites to kill, maybe they'll kill Lucifer at the end of the season.

As to how they get out: Probably either Sam and Dean have Jack get Mary out, and Lucifer jumps out as well, or else Jack decides to get Lucifer out, depending on which side he's on or whether he thinks Lucifer can reform. Because only he can open the dimensional rift, or else Lucifer would have teleported out.

I guess he didn't kill Mary yet.

So, what do you think will happen?
