In the last episode of Supernatural, "Stairway to Heaven," angels were committing suicide in the name of Castiel's army. The brothers began an investigation and though neither of them was sure if they could believe Castiel's claims that he had nothing to do with the angels' deaths, they gave him the benefit of the doubt.
Soon, Dean discovered that one of their old friends, the reaper Tessa, was a part of the unusual faction. That discovery led to a terrible moment when Tessa used Dean's own First Blade to kill herself at his hands. In the end, they found out it was all a trick used by Metatron, but not before the damage was done. Not only was Tessa dead, but the angels had stopped following Castiel and Sam was furious at Dean for bringing the Blade with him in the first place.
The biggest shock came in the final moments of the episode when Gadreel came to make peace and Dean went insane and tried to kill him. Did Gadreel survive the attack? We'll have to wait for the Season 9 finale, "Do You Believe in Miracles," to find out.
The finale airs on Tuesday, May 20. Here is the official synopsis of the episode from The CW:
Dean (Jensen Ackles) feels the effects of the First Blade, and Metatron (guest star Curtis Armstrong) makes his move against humanity. Meanwhile, Sam (Jared Padalecki), Dean and Castiel (Misha Collins) face shocking consequences when taking the fight to Metatron (guest star Curtis Armstrong).
