Apparently, the idea of alternate universes is not a new concept for Michael…or Kevin.

Kevin Tran is back!

Well, sort of.

War of the Worlds

Its not the Kevin Tran we know and love, but rather its Apocalypse Worlds version of Kevin.

Yes, hes still a prophet, which is why hes been annotating the angel tablets to help Michael.

So naturally, Michael steals some from Lucifer.

Speaking of paradise world a.k.a.

And because angels arent big on strangers, he convinces Sam and Dean to stay behind.

But because the Winchesters suck at doing nothing, the two of them decide to work a case.

It seems someone is killing witches in a ritualistic fashion.

And that someone just so happens to look a whole lot like Mr. Ketch.

But it cant be Ketch…right?

Because Mary put a bullet in his head…right?

Long story short, the boys arent sure if its Ketch.

But Deans not buying it.

And theres still the question of why this guy was killing witches in search of Rowena.

As for that front desk clerk, well, Asmodeus has him in Hell.

But when the front desk clerk proves to be a dead end, he kills the poor guy.

(Or rather, one of his demons does.)

Asmodeus then senses something…or rather someone.

And that someone is Lucifer, back in the real world and currently saving Castiel.

Let me explain: Castiel meets his angel friend at the playground to ask if heaven has Jack.

She assures him that they dont, because if they did, theyd put him to work.

If they had Jack, maybe he could create more angels.

He might not have all his grace, but he manages to fool these guys.

(The best line of this episode?

Lucifers oh my dad.)

(It seems Asmodeus isnt ready to give up his position in Hell just yet.)

Its been Arthur all along.

Hes separated from the British Men of Letters and will be killed if they find him.

Because of that, hes going by Alexander.

But shes dead…or is she?

After all, if Michael is coming to their world, theyre going to need Jack.
