God had sent Amenadiel to bless the Decker's, so that she could have a child this transpired to be Chloe Decker, the Goddess sees this reality as the way, of finally convincing Lucifer to take both her, and Amenadiel back home to heaven.
There had been a psycho plaguing Los Angeles who had been targeting individuals, and terrorising them by forcing them to mutilate themselves, to save another innocent human being.
The police finally tracked him down with Lucifer saving yet more victims, while Detective Decker chased and cornered the psycho, sadly he managed to stab her, with poison before he killed himself.
Chloe Decker, Lucifer and Dan have been trying to locate the antidote, and Chloe had asked them not to divulge to Ella Lopez that she was the next victim, while still needing her expertise to help on the case.
Chloe Decker has been injected with a poison designed specifically for her, and the only person who knows the antidote, is the psycho who is currently languishing in hell.
Lucifer called Amenadiel, the Goddess, Maze, and doctor Linda Martin, to formulate a plan to help Chloe. Unfortunately the Goddess thinks, that their plan is ludicrously dangerous, and refused point blank to waste her time, "trying to save a worthless human".
As part of the 'Plan' the relatively simple part was for Lucifer, to meet the psycho and persuade him to reveal the antidote, but regrettably no one had actually worked out how he was going to actually return.
Lucifer was certainly not expecting to be reunited with his deceased brother Uriel, nor to be trapped in his own personal hell loop, of being forced to reenact his murder of Uriel.
Surprisingly despite her protestations the Goddess decided that she wanted to help her son Lucifer after all, when she arrived she admitted to Lucifer what she had been trying to do all along, and decided that she wanted to stay with her son Uriel.
