Cersei Lannister: I'll never leave my son. Olenna Tyrell: What'll you do, then? You have no support. Not anymore. Your brother's gone. The High Sparrow saw to that. The rest of your family have abandoned you. The people despise you. You're surrounded by enemies, thousands of them. You're going to kill them all by yourself? You've lost, Cersei. It's the only joy I can find in all this misery.
