Season 5

Season Five consists of 22 episodes and was rumored to be the last season, due to Eric Kripke's statements over the years that he had planned for the show to run for only five seasons. Despite this, Jared Padalecki and Jensen Ackles had contracts for a sixth season, and The CW renewed the series on February 16, 2010.

Season Summary
The fifth season revolves around the fight to stop Lucifer and save the world from the Apocalypse. Throughout the season, Sam and Dean Winchester battle both angels and demons as they fight their destiny to become the vessels of Michael and Lucifer. Unable to defeat Lucifer, they collect the rings of the Four Horsemen of the Apocalypse, which act as the keys to Lucifer's Cage. The idea of destiny versus freedom and choice plays a large role. Throughout the season, Dean, Sam, Castiel, and Bobby Singer each have a crisis as they near giving up. However, through each other's support, they continue forward until the end. Castiel rebels against Heaven for Dean in this season. It is also notable that Bobby and Castiel have an ongoing friendship during this season, while Dean and Sam grow further apart.
