I have added dialogue for when Sety is on the map at the end of Chapter 4x.

Chapter 4x was one of those chapters that ended without saying anything in vanilla. Since we have conquered the map, we want someone to say something. Wouldn't you? So I added a hint dialogue that Sety will reappear in Chapter 6.
If Sety is not on the map (if you had escaped carrying Sety), he will say another line of dialogue.
