Nah, her first stop back was to kill that River lord guy (I can't be assed to remember names). I really hope she drops some big names.
We've seen she can disguise herself perfectly, and she can easily best a top-tier swordsman triple her size. I want to see what else she's capable of now. She's been my favorite character since the beginning...I need to see her final form.
Walder Frey is the man who ruined her life, at least after Joffrey. Of course she'd go after him. Her list is pretty much burnt out these days aside from Cersei.
