Dean investigates a case in Rexburg, Idaho, where people are seemingly exploding into pink mist. He discovers that a "Ritual Man" (a Rit Zien angel) is responsible.

The episode explores the vulnerability of the supernatural when forced into a natural world.

While Sam remains at the bunker (secretly being healed by the angel Gadreel), Dean is forced to lie to both Sam and Castiel, deepening the wedge of secrecy between the protagonists. Critical Reception

The Rit Zien’s presence suggests that human suffering is so profound that even a celestial being can no longer distinguish between temporary sadness and a terminal soul-wound.

Heaven Can’t Wait is the sixth episode of the ninth season of the long-running dark fantasy series Supernatural . First aired on November 12, 2013, the episode marks a significant tonal shift for the character Castiel as he navigates the mundane complexities of human life while a new celestial threat emerges on Earth.
