Jaime will have some serious explaining to do.
Now that Jaime Lannister is presumably headed toward Winterfell to assist in the Great War, he is going to have a lot of explaining to do. Firstly, to the Starks, for aiding in the imprisonment and death of their father and other family — and particularly to Bran, whom he maimed irreparably back in season one. And secondly, Jaime will have to explain himself to Daenerys Targaryen for killing her father; she despises him. And considering that he tried to rush at her and kill her on the battlefield, Daenerys will likely want to "dracarys" him on sight, so we'll see whether Jaime survives his field trip up North.
