Tyrion despite fighting for Daenerys still loves his brother and Bronn. It would be nice if he would somehow convince them to switch sides - I assume they won't drown and will be captured. Or maybe they will use Jamie as bargain chip to convince Cersei to give up Kings Landing without fight?
Cersei won't give up ****, she knows in the game of thrones you win or you die, she ain't gonna get all soft all of a sudden and give **** up.
