Season 5 may contain attempts to remove Juliette's power. The will even be points when Juliette has to defend keeping her powers. But at this point you can't go back. If watching Juliette mental anguish when login her old life. Losing her powers would be even worse. Unless like Adalind her powers get her in so much trouble she also want to get rid of them. Even Adalind said her mother reached a point where she thought of giving up her powers.
The best we can go for is Juleitte coming to grips with just because she can does not mean she should. What Adalind is going through now. Adalind is realizing having power has only caused her problems. But then Adalind thought is would be fun to be a bad ass hired gun. Like she said how many of use have not beat up a bar.
I just hope they settle Juliette down to be more like Elizabeth, or Henrietta instead of like Adalind. Would be interesting if Adalind actually does become the one the helps Juliette get a hold of being a hexenbiest instead of being a monster that needs to be put down.
That is what season 5 will be for Juliette. Her coming of age being a hexenbiest. Juliette needs to find her place, figure out what her furture holds. See spent years developing a life, a life that had a planed furture. Now all of that has changed. She needs to find a new path. Juliette has shown she believes in destiny. She believes that things happen for a reason. It will start to come to her, she is a hexenbiest for a reason, and that reason is not to make life misserable for everyone.
Juliette will never again be the goody goody character she used to be. She will be tyhe object of conflict and not just a bystander that get caught in the backlash. She will be the cause of conflict rather then it's victim.
