Sources tell TVLine that the supernatural-tinged procedural’s sixth and final season will run a total of 10 episodes — or six less than Season 5, which released its first batch of episodes on Aug. 21. (Season 5 originally and famously received a 10-episode order, but that got expanded to 16 and is being released in two halves.) This final salvo of 10 episodes will bring the series’ grand total to… 93.

Work on season 5 was 95% done, according to exec producer Chris Rafferty, prior to production being shut down over the pandemic. With the TV industry cranking back up again, though, it’s been confirmed that Lucifer will be one of the first shows heading back to shoot. Warner Bros. Television is currently eyeing a start date of September 24th and the first job is to complete the second half of the season finale,
