This battle needs to happen in season 4 part 2

Lord Ras and Beatrix have both evolved far beyond what they were in Season 1. Beatrix has transformed into a monstrous being while Ras is further in his plan and in my opinion far more dangerous then what he was(especially with the three icons). Beatrix confronting her once right hand only for him to call her useless and only a pawn in his true master's plan would be a really good scene imo. Beatrix would say something calling Ras pathetic and saying she should have never trusted an outsider...
