I’m also going to come right out and say that I HATE how they’ve made Cersei so openly disgusted by Jaime’s lack of hand.
In their initial reunion, she says:
"You look so thin. and your hair, your golden hair…"
"The hair will grow back." Jaime lifted his stump. She needs to see. “This won’t.”
Her eyes went wide. “The Starks…”
[snip for irrelevant dialogue/exposition]
She kissed Jaime’s fingers. “You’ll kill him for me, won’t you? You’ll avenge our son.”
Jaime pulled away. “He is still my brother.” He shoved his stump at her face, in case she failed to see it. “And I am in no fit state to be killing anyone.”
"You have another hand, don’t you?"
Cersei is not disgusted by Jaime’s injury. As she later says, “I was afraid the Starks would send me your head.”
She does recoil from his stump later on, after their encounter on the altar. But it should be noted that she recoils after he’s said they should run away together and get married. Jaime infers that she’s recoiling from his stump, but it could be that she was recoiling from what she viewed as something dangerous. Jaime wanted to “stand up before the realm” and admit that they were lovers.
“Don’t…don’t talk like this. You’re scaring me, Jaime. Don’t be stupid. One wrong word and you’ll cost us everything. What did they do to you?”
"They cut off my hand."
"No, it’s more, you’re changed."
Later, Cersei comes to Jaime because Tywin is going to send her to Casterly Rock, force her to marry again, and she says,
"I will not have another husband. You are the only man I want in my bed, ever again."
"Then tell him [Tywin] that!"
She pulled her hands away. “You are talking madness again….I want to be your wife, we belong to each other, but it can never be, Jaime. We are brother and sister.”
"We are not Targaryens!"
"Jaime," she sobbed, "don’t you think I want it as much as you do? It makes no matter who they wed me to, I want you at my side, I want you in my bed, I want you inside me. Nothing has changed between us. Let me prove it to you." She pushed up his tunic and began to fumble with the laces of his breeches.
And then he stops her, says no, not here, not in the White Tower. She says they did it in the sept, why not here? And he stops her again.
For an instant he could see confusion in her bright green eyes, and fear as well. Then rage replaced it.
And THEN she mocks his hand. THEN she lashes out at him for no longer having a sword hand. Only when he’s rejected her, when she feels she has to hurt him like she’s been hurt. When she feels utterly abandoned.
Is there manipulation in all of this? Of course. But to have Cersei so openly reject Jaime on the show, when all he wants is to be with her….does not sit right with me.
