Perhaps most impressively, considering "Torn and Frayed" was mostly just a typical search and rescue mission, the episode featured plenty of development on the mythology front without feeling too heavy-handed.
While "Supernatural" has featured some interesting character developments over the past few weeks, the season's mythology has taken a backseat since episode 802, so it was great to rejoin that arc so decisively with "A Little Slice of Kevin."
This week's "Supernatural" did some things spectacularly and dropped the ball on others, but the episode did serve to drive the narrative forward, as well as delving deeper into Dean's time in Purgatory and giving us our first glimpse of Castiel.
The boys are back in town -- and thank Chuck for that -- since it seems like collective anticipation for Season 8 has reached boiling point over the past couple of weeks. It will be nice to finally lay a few fears to rest and witness exactly what new showrunner Jeremy Carver has planned.
