One of my favourite GoT scenes. Closely followed by Cersei introducing Sept Unella to Ser Frankenmountain...
Cersie, "I said my face would be the last thing you saw before you died, do you remember?
Unella, "Good. I'm glad to see your face. I'm ready to meet the Gods".
Cersie, "What? Now? Today?! You're not going to die today. You're not going to die for quite some time. Sir Gregor!"
(The Franken-Mountain walks in and removes his helm).
Cersei, "Your Gods have forsaken you. This is your God now".
(Unella begins screaming as Gregor bends over her. Cersei closes the dungeon door as she walks out)
Cersie, "Shame!...Shame!...Shame!"
