The pair don't meet again until the seventh season after the Lannister defeat at the Battle of Goldroad. At this point in the series, Tyrion acts as Hand to Daenerys Targaryen while Jaime commands the Kingsguard for Queen Cersei Lannister. Bronn arranges a meeting for them in the catacombs of the Red Keep. The meeting is rife with tension because Tyrion killed their father during his escape from King's Landing, igniting his brother's distrust and Cersei's venom. Tyrion defends the move and explains his return comes on behalf of Daenerys, who requests a ceasefire so their combined forces can work together to defeat the White Walkers.
Jaime reluctantly agrees, and the Dragonpit armistice takes place in the weeks that follow. Naturally, Cersei remains unmoved by the tales of White Walkers and the wight demonstration that follows. Jaime attempts to convince his sister to provide aide to the Targaryen forces, but he fails to move her. When Tyrion arrives to make the same plea, the brothers share a moment of mutual admiration. They acknowledge that they trust each other despite the battles ahead and that past grievances no longer matter.
