The ending of Season 2 of Lucifer left a lot of things up in the air. Lucifer, after dealing with his mother, decides it's time to come clean to Chloe and tell her everything. But before he can get there, he is knocked out cold. He then later wakes up in the desert, shirtless, with his wings reattached. This, of course, leads to the questions of how this will affect him and the upcoming season. Is he an angel again? How did he get the wings back? But the question that pops into my mind is: who knocked him out? The answer to that will be addressed in the new season, it appears.
TVLine is reporting that "the Fox series is casting the recurring role of what is being dubbed 'Sinnerman,' a slightly depraved criminal mastermind whom Lucifer suspects of kidnapping him at the close of Season 2." The refer to this as one of the mythological elements of the series.
This isn't the first time that series has tapped into the name Sinnerman. In Season 1, when Lucifer's shipping contained is being stolen, Tom Ellis is shown in his club singing the Nina Simone song of the same name (one of my all-time favorites). The container of course was very important to Lucifer, as it was where he kept his wings and their theft was a major part of the story for a few episodes.
Lucifer Season 3 debuts on October 2nd.
