“Supernatural” shifted course a bit suddenly with this episode. As viewers were expecting the season to build to a final confrontation between the Winchester boys and Eve (Julia Maxwell), “the Mother of All,” it turns out that Eve won’t even make it to the season finale. In fact, she fails to make it out of this episode.

Ending Eve’s storyline this early was a bit surprising, but when it was revealed that Crowley (Mark Sheppard) and Castiel (Misha Collins) have been working together, it becomes apparent that Eve was not much more than a red herring this season.

The episode was solid and sets up Castiel and Crowley as an unlikely yet charismatic set of foes for Dean (Jensen Ackles) and Sam (Jared Padelecki) to fight over the remaining weeks of the season. While the pairing seems a bit awkward and unlikely, Eve failed to inspire much of a reaction in her limited screen time. At least the Winchesters really hate Crowley, making his role as a villain all the more meaningful.

Points Of Interest

“Mommie Dearest” is the name of a book by Christina Crawford, detailing the abuse she suffered at the hands of her famous mother Joan Crawford.

What Worked

Killing off Eve was a good move. For some reason she just failed to inspire much fear. Walking around in a white dress with blood on it might be creepy, but evil? As an arch villain, Eve lacked the charisma needed in a nemesis. It’s no surprise that they brought back Crowley.

I absolutely loved it when Dean named the hybrid creatures Jefferson Starships, because they are “horrible and hard to kill.” It was even funnier how Sam and Bobby (Jim Beaver) quickly accepted and started using the name for the monsters.

What Didn't Work

Bringing back Crowley. While he is a charismatic villain, it would be nice if someone on this show stayed dead once in a while.

Why can’t the writers just let Mary Winchester (Samantha Smith) rest in peace? Having Eve change into her image was largely pointless.
