1.) This was the end of season 6. The battle between Jon Snow & Free Men army against the Bolton + (?) army at Winterfell. Before the battle began, Ramsey was playing a game with Rickon. He's like "Go run to your brother. Hurry up." Then fired 2 fake arrows at him, then hit him with a real arrow right in the chest probably 20 feet away from Jon. He died, then Snow lost his shit and charged the Bolton army, ruining all of the prep work they had done to ready their own army for the coming battle (digging pits and such).
2.) Season 7, Episode 2. Arya was headed to Kings Landing when she stopped by the inn that Hot Pie went to (in The Riverlands) after being freed from the Lannister prison. He had given her a dire wolf shaped bread back when he first settled there. He asked if she was on her way up to Winterfel and she responded that there was no reason for her to go there while the Bolton army controlled it. He told her that Jon had been victorious over the Boltons and now he and Sansa ruled it and Jon was now 'The King of The North'. So she decides against going to Kings Landing right away, and heads north towards Winterfell. While riding, she stops to make a fire and eat some food. Her horse starts freaking out and both she and the horse get surrounded by 8 wolves. She's holding Needle ready to fight, when Nymeria walks up. Arya realizes it's her and tells her she's headed home and she should come also. Nymeria turns around and walks away, taking all of the wolves with her. Both Arya & her horse are untouched. Arya comments that "It isn't you" to go back home. That's the last we've seen of her.
