So it's all about the soul power?

The soul has been a key element of season 6. First, with the search for Sam's missing one and then, with the race to gather as many souls as possible. That little thing has a lot of energy.

So, "Mommy Dearest" combined this particular plot line with Eve's agenda.

Unfortunately, Eve's arrival as the all powerful Mother of All seemed to come and go rather quickly. Was she actually that easy to kill? Did Dean really eliminate her or like every major enemy, will she return for one final attack?

If that was the final confrontation, then frankly her character was never that large of a threat. Sure, she could create hybrid creatures to attack the entire world for her own collection of souls. Yes, she was the cause of all of the monsters that Sam and Dean hunt. Yet, in the end, her presence felt so absent that she seemed more like a fleeting monster of the week.

Nevertheless, Eve did bring all of the major characters together. Sam, Dean, Castiel, and Bobby all garnered realatively equal amounts of screen time, leaving no one to the background. Plus, they were able to go on an actual mystery hunt that required all of their efforts.

Of course, the hunt also showed off Sam and Dean's greatest strength and weakness. The boys' ability to protect and help others at the cost of themselves is what makes them heroes. It can also end up being one of their greatest downfalls.

Castiel managed to call them out on this concept, which wasn't brand new, but significant nonetheless. However, Castiel really wasn't in the position to be making judgement calls.

Really Cas? You and Crowley working together? So that's the dirty little secret that's been murmuring around in Heaven.

It was a pleasant surprise to find out that Crowley had survived, but that also meant that Castiel was behind the deception of his death. Crowley appears to be that much more of a threat now. If he has one of Heaven's most powerful angels on his side, then Sam and Dean need to worry. Hopefully, they won't have to face off against their friend.

As much as there were big reveals for the night, the episode still managed to toss in a few laughs. While not as many one liners, Dean stole the show with his scientific naming of the new hybrid creatures: Jefferson Starships.

Not only was it a funny name for the monsters, but it was humourous hearing the members of the group shout it out while trying to remain serious. It was just another classic Dean moment.

Overall, a fair episode, but it would have been nice to see Eve stick around a little longer. Compared to the other enemies of seasons past, she came across as the weakest of the bunch. It's just too bad she wasn't the menace that everyone claimed her to be.
