Here's season 9 everyone. All in all, I think it was a pretty good one, there's actually 23 episodes this season instead of 22. Probably to make up for wasting an episode on that ill-advised spinoff pilot....

Bloodlines (Episode 20)
Note: This episode was supposed to be a backdoor pilot for a spin-off series and well....it didn't do so well so honestly you could skip this episode and not miss a thing.
A young man discovers that not only are there things that go bump in the night but also that Chicago is ruled by five monster families (not too bad of an idea but very very poorly executed). While doing his own investigating he runs into our favorite hunters, Sam and Dean (who are seriously only in this episode for, like 5 minutes in total.)
King of the Damned (Episode 21)
Cas asks Dean and Sam for help with interrogating one of Metatron's followers for information about the portal to Heaven. While they are doing that, Cas tries to convince Gadreel to change sides. Also Abbadon uses Crowley's humanity, brought on by his addiction to human blood, to pressure him into leading the boys into a trap.
Stairway to Heaven (Episode 22)
Angels following Cas start turning themselves into suicide bombers saying they are doing this under Castiel's orders. While Dean stays behind to interrogate a captured bomber, Sam and Cas go to find a missing angel who may be involved. Revalations about Metatron's strategies cause Gadreel to contemplate his loyalties.
Do You Believe in Miracles (Episode 23)
So much goes on in this episode that is spoiler-y but sufficed to say, the big fight against Metatron goes down and there is a major casualty. Also the last five seconds proves, once again, the folks at Supernatural know how to do an amazing cliffhanger. (Fall is way too far away...)
