This episode probably shouldve been called Jack out of the Box with that ending.

I had to.)

But before we get into all of that, we start the hour witha memorial for Maryat the bunker.

She could handle a machete.

She could handle a vampire.

She could handle our old man.

She couldnt cook worth a damn.

Mom, you werent here long enough, but were so glad for the time that we had.

Talk about an entrance!

And now that Bobby is here, he wants answers: What the heck happened to Mary?

The way Bobby sees it, Jack is an unstoppable monster who doesnt know right from wrong.

And that means he needs to be put down.

With that in mind, Castiel heads to heaven for help.

Thats where Duma lets him know that shes now in charge.

It seems that after the Empty invaded under Naomis watch, Naomi was locked up.

(That seems like a not-great decision considering how few angels there are left, no?)

But Duma promises to help Castiel finds Jack.

Then again, Duma is a big liar.

Spoiler: She does find Jack, but she doesnt tell Cas about it.

First, he turns an atheist professor into salt.

Then he kills a TV evangelist with a personalized sinkhole.

(Numbers 26:10 And the earth opened her mouth and swallowed them up.)

The only bit of good news about Jacks new hobby is that it makes him easy to find.

Sam quickly flags the killings, and when Jack leaves a victim behind, they learn more.

So, he takes them to heaven and turns them to angels.

But when one person among them doesnt believe, he leaves him to be eaten by worms.

(Its another Biblical thing.)

There, the guy IDs Jack and explains that hes carrying out heavens orders.

So while Castiel works on getting back to heaven, Dean comes up with a plan of his own.

Well, it was built to contain the power of an archangel.

So if they can convince Jack to get into it, theyll be safe.

But how do they convince him to get into it?

Dean wants to tell Jack that theyre close to finishing a spell that will fix his soul.

As much as Sam hates the plan, he knows they have to stop Jack.

And while Jack listens to Sams prayer, Castiel pulls Duma aside for a chat.

(Again, as much as I support Castiel, maybe we should stop killing angels?!)

However, by the time Cas returns to Jack, hes gone…

Because hes in the bunker.

Jack updates Sam and Dean on what hes been doing and he tells them that he regrets the accident.

I wish it didnt happen, he tells them, lacking the emotion one needs a soul to express.

Sam and Dean do their best not to snap, to pretend that they forgive him.

And ultimately, they tell him about the fake spell and convince him to get in the box.

And much to their surprise, Jack gets in willingly.

At least at first.

Jacks subconscious pays him a visit in the box and lets him know that hes been played.

You are screwed, Lucy tells him, encouraging Jack to use all of his power to escape.

And he does just that.

So … what now?

Overall, this episode feels like a solid setup heading into the finale.

Up until this point, hes still been on Sam and Deans side.

But what happens if Jack truly goes to the dark side?
