What is going on with Farnese in the end of the 6th deluxe book (book 18)

Ok so I just finished it about 5 minutes go, and what the hell is Farnese doing man. Like is she turned on from getting people killed, watching people get killed, or like what. I have no clue what is going on with her man. As of right now I don’t like her that much but I do know she’s gets better but like still what is she doing???
