[EX Q]: In Game of Thrones s08e04 we see Varys and Tyrion having a conversation about who would be the best heir for the Iron Throne where Varys seems to try to conspire against Daenerys. Here are the last phrases of their dialogue:    Varys: You know where my loyalty stands. You know I will never betray the realm.    Tyrion: What is the realm? Vast continent home to millions of people most of whom don't care who sits on the Iron Throne.    Varys: Millions of people. Many of them will die if the wrong person sits on that throne. We don't know their names but they are just as real as you and I. They deserve to live. They deserve food for their children. I will act in their interest no matter the personal cost.    Tyrion: So what happens to her? Please ... don't ...    Varys: I have spoken as honestly as I can. Each of us has a choice to make. I pray we choose wisely.   What does Varys's last words exactly mean? What is he planning to do? Does he imply something specific?
