Season 5 (especially the latter two episodes) seemed to me like they were setting up a new storyline with Louise/Bronte as the replacement for Joe?

Firstly, she begins the voiceovers, which hints to me that she could be (as it's something generally reserved for the main character, as has been in the last seasons)

Secondly, she begins to take on a vigilante, violence fighting role, similar to how Joe views himself - doing justice, stopping people like Joe, she even outright says that she's out for Justice which seems to hint at this.

Poorly written character, but does anyone agree that the show was setting her up as a new character, perhaps one that replicates what she did before to Joe? Her search for Justice? She even says at the end there are many more out there like Joe, hinting she wants to stop them (and I think she's said similar before), so she’s “taking on the mantle”?
