Following the release of [[the Darkness]], cries are heard coming from the Cage, and the demons speculate that Michael or Lucifer are trying to warn them about it. Sam also starts having flashbacks or visions of his torment in the Cage. When Sam finally journeys to Hell to confront Lucifer with [[Crowley]] and [[Rowena]], he learns that the impact of the Darkness' release had a massive effect on Hell, causing the Cage to become damaged. It was through those fissures Lucifer was able reach out and give Sam his visions of the Cage. Lucifer is eventually able to escape in [[11.10 The Devil in the Details]] by taking [[Castiel]] as his [[vessel]], leaving Michael, who had become catatonic due to his imprisonment, alone in the Cage.
In 2020, God opens every doorway in Hell to unleash the souls of the damned into the world, including Lucifer's Cage. Eventually, Michael is revealed to have maintained his sanity and escaped from the Cage when it was opened, leaving it empty.
