We don't know (and may never find out) all that was said between Cersei and Tyrion Lannister after the Dragon Pit meeting at the end of season seven of Game of Thrones.
But we do have a clue as to whether the Tyrion-Jaime-Cersei sibling rivalry will ever work itself out. Will Tyrion betray Dany in order to stay loyal to his family name of Lannister? Or will he betray the dragon queen due to jealousy? (He looked pretty upset when he stood outside the room of the ship where Jon and Dany were gettin' it on...)
Speaking to TV Guide about season eight, Peter Dinklage and Nikolaj Coster-Waldau revealed that Tyrion and Jaime are going to end up working things out.
"There is no future without defeating the threat," Coster-Waldau said, even though he believes Cersei is staying behind to protect their unborn child. And Lena Headey also weighed in and confirmed as much.
