Game of Thrones, Season 7

Petyr Baelish:
Lady Sansa, I have known you since you were a girl. I have protected you...

Sansa Stark:
Protected me? By selling me to the Boltons?

Petyr Baelish:
If we could speak alone, I can explain everything...

Sansa Stark:
[quoting Petyr] "Sometimes, when I'm trying to understand a person's motives, I play a little game. I assume the worst." What's the worst reason you have, for turning me against my sister? That's what you do, isn't it? That's what you've always done. Turn family against family, turn sister against sister. That's what you did to our mother and Aunt Lysa, and that's what you tried to do to us.

Petyr Baelish:
Sansa, please.

Sansa Stark:
I'm a slow learner, it's true. But I learn.

Petyr Baelish:
Give me a chance to defend myself. I deserve that. [to Yohn Royce] I am Lord Protector of the Vale and I command you to escort me safely back to the Eyrie.

Yohn Royce:
I think not.

Petyr Baelish:
[kneels before Sansa] Sansa, I beg you! I loved your mother since I was a boy!

Sansa Stark:
And yet, you betrayed her.

Petyr Baelish:
I loved you. More than anyone.

Sansa Stark:
And yet, you betrayed me. When you brought me back to Winterfell, you told me "there's no justice in the world, not unless we make it." Thank you for all your many lessons, Lord Baelish. I will never forget them.

[Arya steps towards Littlefinger]

Petyr Baelish:
Sansa--
