A couple of my favourites:
Needle was Robb and Bran and Rickon, her mother and her father, even Sansa. Needle was Winterfell's grey walls, and the laughter of its people. Needle was the summer snows, Old Nan's stories, the heart tree with its red leaves and scary face, the warm earthy smell of the glass gardens, the sound of the north wind rattling the shutters of her room. Needle was Jon Snow's smile. He used to mess my hair and call me "little sister," she remembered, and suddenly there were tears in her eyes.
Seven, Brienne thought again, despairing. She had no chance against seven, she knew. No chance, and no choice.
She stepped out into the rain, Oathkeeper in hand.
The Princess in the Tower:
She narrowed her eyes. "What is our heart's desire?"
"Vengeance." His voice was soft, as if he were afraid that someone might be listening. "Justice." Prince Doran pressed the onyx dragon into her palm with his swollen, gouty fingers, and whispered, "Fire and blood."
Honourable mention to like... Cersei in general, Jaime and Genna's conversation, and Brienne meeting Lady Stoneheart.
e: Oh, and Brienne's conversation with the Elder Brother.
