( Spoilers main) what will Cersei’s vengeance be?

Lannisters always pay their debts. My big question is , now that she has been shamed and humiliated, how will Cersei avenge herself agaisnt the people who did that to her? The tyrells? The high septon? The nuns who made her walk? The small folk?

When we last saw her she had a zombie Gregor Clegane carrying her.

Wierdly enough I think the show might have gotten it right. She will use Gregor to kill off a lot of people and might well get rid of the tyrells and sparrows in a spectacular fashion.

What do you think?
