4. Dan’s redemption
If any person has done the whole two steps forward, two steps back that allows for audience empathy to remain, then it’s the lovingly nicknamed Detective Douche.
After working to improve himself following his corrupt beginnings in season 1, Dan backslid pretty hard in season 4 following Charlotte’s death. A lot of it was Dan blaming Lucifer (and himself) for her death. While he didn’t go full-on corrupt cop of season 1, he did leak Lucifer’s name to a man in hopes that he would kill him. In the process, he inadvertently placed Trixie in danger.
Toward the end of season 4, it did look like Dan was taking to deal with his issues and get back to the better place that he was in during seasons 2 and 3. He had a session with Linda, before she went into labor. It looked like that he was able to name some of the issues that were bothering him and why he was projecting them on Lucifer. Dan wants to be punished for the bad things that he’s done, but it seems like the universe doesn’t want him to.
In season 5, we think that Dan will continue down this path. Hopefully, he gets to a place where he can forgive himself. As everyone knows, it’s guilt that will damn a soul to Hell in the series. All you need to do is free yourself of it. Dan does deserve to see Charlotte again one day.
3. Lucifer accepts his free will
One of the defining traits of Lucifer is his desire of free will, making his own decisions without the influence of God in his life. It’s something that Lucifer has struggled with over the course of the series, trying to have that freedom and make his own choices. While many believe that he does have the power to make his own choices, that he has what he wanted this whole time, Lucifer needs to believe it himself.
In the final season of the series, Lucifer needs to, in some way, decide that he has free will and has always had it. He needs to make his own decisions. Now giving form to an abstract concept is difficult, but Lucifer writers have done it before.
Truth be told, for those of who read the comics, this version of Lucifer exercises a lot more free will than his comic counterpart has ever done. He is free, but he just doesn’t realize it due to being too scared of being controlled to acknowledge it. Fear prevents him from realizing his freedom as it does for us all.
It’s an interesting internal struggle. If he returns to his sessions with Linda, then it will definitely be something that should be touched on in therapy.
