This week’s Supernatural, “Remember the Titans”, taps into Greek Mythology for an entertaining tale about Prometheus, his deadly curse, and the god who put it on him, Zeus. But after so many Men of Letters stories, are Sam and Dean ready for the return of Castiel and God’s trials?

After Sam and Dean begin investigating an apparent zombie sighting nearby, the Winchesters are surprised when they find out that the undead person is actually Prometheus, the Greek Titan who Zeus cursed with having to experience death each day. But when a mysterious woman shows up at Sam and Dean’s with a little boy and stories of once loving Prometheus, everyone comes together to figure out a way to get Zeus to remove Prometheus’ curse, which has now infected his son.

It should be no surprises to fans that after weeks of exceptional episodes, the second-half of Supernatural season 8 is still cranking out top-level stories rich with theology and mythology. This week, a surprisingly astute zombie-twist was coupled with the age-old tale of Prometheus, the cursed Titan who created man out of clay and stole the fire of the heavens to aid humanity. And since Supernatural is always at its best when it delves deep into legend and lore, the modern-take on Prometheus’ proverbial sequel proved to be as strong of a stand-alone episode as any longtime fan could ask for.

In this this mythological adventure, Sam and Dean, who are better than ever on-screen, are thrown in to a mysterious adventure with dead-then-undead elements, only to have the veil brilliantly pulled back to reveal that the Greek gods are the focus of this episode, not zombies. And with that, much of the episode took on a similar tone where, like with the zombies, the actual story being told is used to sell the premise, not undead beings or promises of a spectacular battle worthy of Mount Olympus. Like any great episode of Supernatural, a solid story always bests special effects.

And although this week’s episode was essentially about Prometheus’s tale of love and fatherhood, the actual foundation that this story was built upon was the mystery of who/what Prometheus was and his relationship with the Father of Gods and men, Zeus. And even though Zeus’ business-dressed portrayal was less godly than many would expect from, you know, Zeus, his unshakable thirst for vengeance and continuous revelry in pain and suffering served as the perfect antagonist to Sam and Dean’s heartwarming mystery about a Titan-turned-father.

But like last week’s episode brought to light, Supernatural has been straying far off of its initial season 8 story, the Word of God and the Gates of Hell. So while Sam and Dean’s adventures have truly been enjoyable, even anticipatory, each week, there’s still a lingering question about the series’ ability to pull all of the many story elements together for a cohesive, hopefully logical, conclusion to its eighth season.

To Supernatural’s credit, there hasn’t been a single element in these returning episodes that show the series is not up to such a challenge. If anything, the Golem, the familiar and the Titan storylines could be seen as “tests” for the writers and producers. If, by chance, an aging series on the lowest-rated broadcast network is able to craft beautiful stories around characters that are new to the series but rich with known mythology, there’s no question that it should be able to return itself to its pre-Leviathan state.

So now that Supernatural’s recent episodes have, in fact, been widely successful, it’s time for the writers and producers to pick-up the storylines that have largely been ignored since the series returned from its winter Hiatus. And if Dean’s prayers to Castiel are any sign, it looks like Sam and Dean will begin taking on heaven and hell again next week.

Supernatural returns next Wednesday with “Goodbye Stranger” @8pm on The CW. You can check out a preview of next week’s episode below:
