I'm guessing by the end of the Aunt Sylvie fight we see the blue man about to kill the arbiter, but then one of his soldiers goes like "but there's no honor in this" and kills the blue man instead. Saurfang saves the day while Aunt Sylvie smokes up and is now the main antagonist in the last raid. Last raid also gets a fully rendered cinematic where Sylvie gets to monologue about life and maybe read a poem or two.
