Event: Tyrion Lannister - Deals Brokered (Political Wins)

Episode 5: Eastwatch at 41:13
After Tyrion and Jaime's secret meeting, Cersei agrees to the truce with Daenerys while they await for Jon to return with proof of the White Walker situation.

Cersei: "I've come to believe that an accommodation with the Dragon Queen could be in our immediate interest. She has the numbers. If we want to beat her, we have to be clever. We have to fight her like Father would have."
