Tyrion Lannister: If we marry them, they could rule together.
Varys: She's his aunt.
Tyrion Lannister: That never stopped a Targaryen before.
Varys: No, but Jon grew up in Winterfell. Is marrying your aunt common in the North? You know our queen better than I do. Do you think she wants to share the throne? She does not like to have her authority questioned.
Tyrion Lannister: I sense that you're leading to a proposal.
Davos Seaworth: A proposal is what I'm proposing. On the off chance that we survive the Night King, what if the Seven Kingdoms, for once in their whole shit history, were ruled by a just woman and an honorable man?
Tyrion Lannister: They do make a handsome couple.
Varys: You overestimate our influence. Jon and Daenerys don't want to listen to lonely old men.
Tyrion Lannister: I'm not that old. Not as old as him. (looks at Davos) Our queen respects the wisdom of age.
Varys: Of course she does. Respect is how the young keep us at a distance, so we don't remind them of an unpleasant truth.
Tyrion Lannister: What is that?
Varys: Nothing lasts.
Tyrion Lannister: You should consider yourself lucky. At least your balls won't freeze off.
Varys: You take great offense at dwarf jokes, but love telling eunuch jokes. Why is that?
Tyrion Lannister: Because I have balls, and you don't.
Varys (to Tyrion): I found the traitors, but I wasn't the one burning them alive. I was only a purveyor of information. It's what I told myself when I watched them beg for mercy... I'm not the one doing it. When the pitch of their screams rose higher... I'm not the one doing it. When their hair caught fire and the smell of their burning flesh filled the throne room... I'm not the one doing it.
Varys (to Melisandre): Give us common folk one taste of power, we're like the lion who tasted man. Nothing is ever so sweet again.
Daenerys Targaryen: Swear this to me, Varys. If you ever think I'm failing the people, you won't conspire behind my back. You'll look me in the eye as you have done today, and you'll tell me how I'm failing them.
Varys: I swear it, my queen.
Daenerys Targaryen: And I swear this... if you ever betray me, I'll burn you alive.
Varys: I would expect nothing less from the Mother of Dragons.
Varys (to Daenerys): You wish to know where my true loyalties lie? Not with any king or queen, but with the people. The people who suffer under despots and prosper under just rule. The people whose hearts you aim to win. If you demand blind allegiance, I respect your wishes. Grey Worm can behead me or your dragons can devour me. But if you let me live, I will serve you well. I will dedicate myself to seeing you on the Iron Throne because I choose you. Because I know the people have no better chance than you.
Tyrion Lannister: Lord Varys has proven himself a loyal servant.
Daenerys Targaryen: Proven himself loyal? Quite the opposite. If he dislikes one monarch, he conspires to crown the next one. What kind of a servant is that?
Varys: The kind the realm needs.
Varys: I'll walk the rest of the way myself. I can't go off on a secret mission in the company of the most famous dwarf in the city.
Tyrion Lannister: Varys. The most famous dwarf in the world.
