Arya demonstrates her killer pie making skills:
Season 6, Episode 10: The Winds of Winter
Now, let's talk about that PIE!
After six seasons of this show toying with the Starks, Arya finally returns to Westeros like a BOMB. It's a satisfying moment, a gruesome moment, and a seriously disturbing moment as we watch Arya graduate from a loose cannon to a seasoned assassin. She's not the same girl who took her chances with the down and dirty revenge killings of Polliver and Meryn Trant, she's clearly giving some careful thought to the the method and manner of her vengeful return. A girl has a plan. And that plan involves the baking of a very special pie.
