Theon Greyjoy

— Are you afraid?
— I must be.
— Good.
— Why is that good?
— It means you're not stupid.

— I sent 2,000 men to their graves today.
— The bards will sing songs of their sacrifice.
— Aye. But the dead won't hear them.

— I always wanted to do the right thing. Be the right kind of person. But never knew what that meant. It's always seemed like there was... Like there was an impossible choice I had to make. Stark or Greyjoy.
— Our father was more of a father to you than yours ever was. And you betrayed him. Betrayed his memory.
— I did.
— But you never lost him. He's a part of you. Just like he's a part of me.
— But the things I've done...
— It's not my place to forgive you for all of it. But what I can forgive, I do. You don't need to choose. You're a Greyjoy and you're a Stark.

— The sea is in my blood.
— Your blood will be in the sea if I don't watch where l'm going.

— Ser Rodrik, it grieves me that we meet as foes.
— It grieves me you've less honor than a back alley whore.

Tyrion Lannister: — I still remember seeing my father's fleet burn in Lannisport. I believe your uncles were responsible.
Theon Greyjoy: — Must have been a pretty sight.
Tyrion Lannister: — Nothing prettier than watching sailors burn alive. Yes, a great victory for your people. Shame how it all turned out.

— Any last words, old man?
— Gods help you, Theon Greyjoy. Now you are truly lost.

It's better to be cruel than weak.
