Supernatural has always been something of a journey and each season has essentially marked a specific chapter in that excursion, beginning with the simple hunt for Sam and Dean's father. As the series progressed, the challenges became more difficult, the enemies stronger, the twists more dramatic - but all in all, the Winchester brothers were moving towards something whether it was defeating an enemy or saving the world.

There was always some end game in sight.

After 21 episodes of season seven, Sam and Dean can finally do something about the all powerful Leviathan. Their goal for victory just came within reach.

We knew at some point that the creatures of the black ooze would meet their demise, but for the most part, any indication of that seemed absent. There were moments of borax and beheadings that slowed them down, but nothing that could actually eliminate them.

But why would the writers wait until the final three episodes to set the plan in motion?

Don't get me wrong, searching for the blood of the fallen sounds like a cool but arduous task, but Castiel gave it up last episode, the Alpha vampire gave his up this episode, and now they need Crowley and presto: the weapon is ready.

I know the trouble that the boys are going through to get the blood, and its not an easy task, but to be honest, it's felt like they snapped up the blood mighty quick.

Which makes me wonder, why this grand task didn't happen earlier in the season? Sure, we could have seen the brothers on the run and realize the Leviathan are too strong to defeat, but somewhere in the middle pack of episodes, the recognition of a potential weapon would have given the brothers something to head towards and do, other than just fight random monsters along the way and hope not to get eaten.

Perhaps it would have allowed for more of a fluid continuity story arc wise and we could still have ended up exactly where we are now, but knowing that it was a tough trip for the brothers to get there.

But now that we are there, I feel a sense of certainty, even if I'm not certain the Leviathan will be defeated this season. It really doesn't seem probable, and if Sam and Dean do, would truly illuminate the waste of a bad guy.

"There Will Be Blood" was the stepping stone for the final show down and reintroduced the Alpha Vampire who was so much more scary than Edgar or the rest of the Leviathan. Perhaps it was his piercing eyes, his calm and cool demeanor with an edge of knowing his own power, or maybe it was simply his frighteningly long cuticles. The Alpha Vampire emitted a mystery and ability to crush everything around him, all while sitting in his chair.

It was rather interesting that the Leviathan had made a deal with the Alpha, but double crossed them in the end. Seems that the Leviathan are only out for themselves. Who knew?

Even further so, how Sam and Dean get stuck asking their enemies for help and how their friends have even become their enemies. Castiel paid the price with his mind, but it seems that Bobby is getting closer and closer to vengeful spirit. I've got a feeling he's going to make a sacrifice before the boys put him away for good.

While I'm glad the episode brought back Crowley and the Alpha, and even gave some focus to the Leviathan story arc, I'm still waiting for that big kick that really sets apart the Leviathan as the worst bad guys ever faced. If anything, the finale needs to reinvigorate that sense of urgency and fear so I feel that as the episode draws to its probable cliffhanger close, I'll be excited to see it lead to something more and not simply waiting for it to be wrapped up.

It's time to give Dick a good beat down. Supernatural style.
