After a string of episodes with comedic overtones and a slight departure from the season arc, the main story swings back into action with this installment. While the episode itself has a simple premise, and there are only a handful of surprises along the way, it serves as a gratifying and satisfying setup for the events to come.

In essence, this episode sums up everything that has been hinted since the beginning of the season, reinforcing several plot points while expounding on a few others. Reaction to the episode will vary depending on interpretation of information already available. For example, if the clues regarding the relationship between Sam and Ruby were overlooked amidst the mystery of Dean’s restoration, then the confirmation of their physical acrobatics. (To be honest, I was a little disappointed by the fact that Ruby wasn’t still played by Katie Cassidy in those moments. But I digress.)

Earlier in the season, the erosion of Sam’s morality was apparent, if relatively well-covered by his subsequent choices. His decision to train under Ruby and ultimately sleep with her represents a brand of personal darkness similar to that seen in “Mystery Spot”.
