The Trap opens with Sam chained to a chair in a casino.

Eileen is there, too.

But now he has Sam where he needs him and plans on getting rid of their bullet-wound connection.

Not only that, but hes added a scary and sadistic edge to his performance.

It was genuinely unsettling watching him force Eileen to cut into Sam.

And what he shows them is bleak.

Essentially, the monsters rise because the law of nature takes over when Gods not there.

Unfortunately, the brothers dont get out of the game.

Instead, they end up being turned into vampires and ganked by Jodie and Bobby.

(What a terrible way to go!)

So, the duo follows the piranha mouth to the field.

(Having just re-watched seasons 6 and 7, Ilovedthis callback.)

The Leviathan knock Dean out and carry Castiel away.

When Dean comes to, Castiel is nowhere to be found.

Desperate, Dean decides to pray to Cas.

out of Deans monologue.

I shouldve stopped you.

I dont know why I get so angry.

Of course, I forgive you.

Dean eventually does find a bloody Cas leaning up against a tree.

Oh, and he heard Deans prayer.

For my money, I think Sam and Dean are more Sisyphean.

Maybe, its a combination of both.

Dean and Cas show up at the casino.

Dean hilariously punches Chuck, who responds by punching back way harder.

A newly healed Chuck is a gleeful Chuck.

(Whens the last time Sam kissed someone on this show?)

Then, Sam tells Dean and Cas that he believed the futures Chuck showed him.

Thats enough for Dean.

So Dean says they just need to find another way to fix this problem.

Meanwhile, Billy comes to Jack in the Empty and says, Its time.

Oh yeaaaaahhh, its Jack time, baby!
