Chloe deals with the absence of Lucifer in her life, only for his twin brother Michael to arrive and turn the lives of everyone close to Lucifer upside down bad enough to force Lucifer to leave Hell. At the same time, Ella has something good happen in her life and Maze begins having an existential crisis.
God plans to pass his divine powers onto one of his children so that they can run the Universe. To this end, Michael has gained the support from the rest of the angels, while Lucifer sees this as the chance to fix what he believes to be wrong with the world. At the same time, Chloe and Linda use this opportunity to tell God what a poor father he's been to Lucifer.
