Game of Thrones, Season 1

Robert Baratheon:
Backstabbing doesn't prepare you for a fight and that's all the realm is now: backstabbing and scheming and arse-licking and money-grubbing. Sometimes I don't know what holds it together.

Cersei Lannister:
Our marriage. [both burst out laughing]

Robert Baratheon:
So, here we sit, 17 years later, holding it all together. Don't you get tired?

Cersei Lannister:
Every day.

Robert Baratheon:
How long can hate hold a thing together?

Cersei Lannister:
Well, 17 years is quite a long time.

Robert Baratheon:
[raises glass] Yes, it is.

Cersei Lannister:
[raises glass] Yes, it is. [drinks] What was she [Lyanna Stark] like?

Robert Baratheon:
[shocked] You've never asked about her, not once. Why now?

Cersei Lannister:
At first, just saying her name, even in private, felt like I was breathing life back into her. I thought if I didn't talk about her, she'd just fade away for you. When I realised that wasn't going to happen, I refused to ask out of spite; I didn't want to give you the satisfaction of thinking I cared to ask. And eventually it became clear that my spite didn't mean anything to you; as far as I could tell, you actually enjoyed it!

Robert Baratheon:
So why now?

Cersei Lannister:
What harm could Lyanna Stark's ghost do to either of us that we haven't done to each other a hundred times over?

Robert Baratheon:
[sadly] You want to know the horrible truth? I can't even remember what she looked like. I only know she was the one thing I ever wanted. Someone took her away from me, and seven kingdoms couldn't fill the hole she left behind.
