Rebound?

I think it was obvious that they were going to have to put a huge dent into her forces, she was too strong for Cersei to start the season.

She's going to ask Jon for help, but what can he possibly bring to the table at this point? I think it's obvious (from the trailer) that the dragons are going to do some damage next episode, but on who?

I also think Olenna planted seeds of doubt in Jamie's mind regarding Cersei.. That last scene was one of my favorite scenes in GoT to date.
