Changes

The Winchesters and [[Castiel]] use a spell from one of [[Rowena's Spellbooks]] to enter [[Hell]] in search of [[Michael]]. As the three fight with [[demons]], they are shocked when Rowena interrupts them. Rowena explains that following her death, she was able to seize control of Hell for herself and has now become the new Queen of Hell. Though she knows Michael may not be in Hell anymore, Rowena directs her demons to search for the [[archangel]] and reassures Sam that he did the right thing in killing her. Noticing tension between Dean and Castiel, Rowena, noting her own long list of regrets from life, urges the two to make amends. However, a demon brings word that Michael is no longer in Hell, forcing the Winchesters and Castiel to leave empty-handed.
