Dean's season 8 arc and absence

Jensen Ackles will be back for season 8 as a regular, but the rumors are true we will be seeing less of Dean for at least the first 6 episodes. Dean appears in the first 2 episodes, is completely absent in episodes 3, 4 and 5. Appears in 6 via flashbacks, absent in 7 and cameo in 8, before returning officially into the series during 9.

Season 9 (2015–2016)
The ninth season follows the events in Special Delivery with the birth of Maryann's son. Much of the season explores the beginning of the new Supernatural Files, with both Sam, Laura and Adam. This season begins the changes with Dean and Katherine, with Dean no longer a FBI agent, and Katherine now working at the FBI academy.

This is the first season of the series to feature an episode without neither Dean Harrison or Katherine Winters, which occurs in episode 912. Both Dean and Katherine's limited screentime was to allow the other characters to get focus, and at the request of the actors wanting time off, which was part of the way to get them to sign on for one more season with season 10. Dean is not in the first 3 episodes of season 9, his character having gone into hiding was a ruse when he was really getting information, although in 901 he appears briefly in the opening with no lines. He returns in episode 4, both Dean and Katherine leave town at the end of 911 to get answers, only Dean returns in 913 without Katherine, who was still looking, both tell the group in 916 about the findings. However when fan outrage occurred, both characters would not be missing in season 10, and get a major focus, which in turn includes all main characters taking part in the final battle with Lucifer.
