Tyrion: "I think we ought to begin with larger concerns."
Euron: "Then why are you talking? You're the smallest concern here."

Euron: "They were lesser men."
Cersei: "You have broken promises to allies before and murdered them at the nearest opportunity - you murdered your own brother."
Euron: "You should try it. Feels wonderful."
