I love their relationship dearly. The only trouble I have with the ship is the age. Did Sansa care for Tyrion? I believe so, yes, but I don’t think it was in a romantic way, though I don’t see her falling for him as impossible. On the other hand, Tyrion was clearly falling for her.
I want her, he realized. I want Winterfell, yes, but I want her as well, child or woman or whatever she is. I want to comfort her. I want to hear her laugh. I want her to come to me willingly, to bring me her joys and her sorrows and her lust.
What I love is that Sansa and Tyrion’s relationship isn’t based off of lust or love, but of mutual understanding. They help each other and show compassion for one another, and that is so important because neither of these characters are shown those things very often. They help each other and comfort each other in so many ways.
When Sansa turned, the little man was gazing up at her, his mouth tight, his face as red as her cloak. Suddenly she was ashamed of her stubbornness. She smoothed her skirts and knelt in front of him, so their heads were on the same level. “With this kiss I pledge my love, and take you for my lord and husband.”
His grin turned into something softer as he studied her face. “Is it grief for your lord father that makes you so sad?”
“My father was a traitor,” Sansa said at once. “And my brother and lady mother are traitors as well.” That reflex she had learned quickly. “I am loyal to my beloved Joffrey.”
“No doubt. As loyal as a deer surrounded by wolves.”
“Lions,” she whispered, without thinking. She glanced about nervously, but there was no one close enough to hear.Lannister reached out and took her hand, and gave it a squeeze. “I am only a little lion, child, and I vow, I shall not savage you.”
“I know I am not the sort of husband young girls dream of, Sansa,” he said softly, “but neither am I Joffrey.”
“No,” she said. “You were kind to me. I remember.”
He pushed himself to his feet. “Don’t lie, Sansa. I am malformed, scarred, and small, but…” she could see him groping “…abed, when the candles are blown out, I am made no worse than other men. In the dark, I am the Knight of Flowers.” He took a draught of wine. “I am generous. Loyal to those who are loyal to me. I’ve proven I’m no craven. And I am cleverer than most, surely wits count for something. I can even be kind. Kindness is not a habit with us Lannisters, I fear, but I know I have some somewhere. I could be… I could be good to you.”
So, to put it simply, I think Sansa and Tyrion could be very good for and with each other, if only Sansa were a bit older. But, they truly have changed each other for the good, and their dynamic will always be one of my favorites.
