O show parece ter seguido principalmente o caminho do ex-amante desprezado e, portanto, Shae esquece sua proteção e amizade com Sansa apenas por uma questão de enredo ... como muitas coisas no programa.
TYRION: I'm a married man. My wife has suffered a great deal, as you well know. I don't want her to suffer anymore on my account. I need to uphold my vows.
SHAE: She doesn't want you.
[...]
SHAE: We will fight them together. It's like you said, I am yours and you are mine.
TYRION: You're a whore! Sansa is fit to bear my children and you are not. I can't be in love with a whore. I can't have children with a whore. How many men have you been with? 500? 5,000?
SHAE: How many whores have you been with?
TYRION: I have enjoyed my time with all of them and I have enjoyed my time with you most of all. But now that time is over.
TYRION walks over and opens the door. SHAE sobs. BRONN enters.
TYRION: You'll have a comfortable life in Pentos. Bronn will escort you to your ship.
SHAE continues to sob. BRONN clasps her shoulder to lead her out. She turns quickly and slaps him, then storms off, crying. BRONN looks to TYRION, then exits. TYRION walks to the table and violently slaps his cup to the ground.

E as coisas que ela diz no julgamento novamente indicam que ela está "irritada" por Tyrion se casar com Sansa.
SHAE: I am a whore. Remember? That was before he married Sansa. After that, all he wanted was her. But she wouldn't let him into her bed. So he promised to kill King Joffrey for her.

A implicação, antes que a conversa acima ocorra, também parece ser que Cersei e Tywin notaram o que está acontecendo e interceptaram sua saída. Eles provavelmente usaram o casamento de Tyrion com Sansa e ela foi ferida para manipulá-la para fazer o que eles queriam.
MACE bows and exits. SHAE brings a tray to the table and sets it before SANSA.
CERSEI: She's the whore I told you about. The dark-haired one.
SHAE exits.
TYWIN: Have her brought to the Tower of the Hand before the wedding.
TYRION looks concerned. PODRICK places a large tome before JOFFREY and TYRION walks to the front of the table.

Isso fica ainda mais claro quando Shae é encontrado nas câmaras de Tywin por Tyrion sendo usado como prostituta. Parece incrivelmente provável que Tywin a tenha manipulado para fazer o que ele queria.
INT. TYWIN’S BEDCHAMBER - NIGHT
A dark-haired woman lies atop the bedclothes, her face turned away from us, naked save for the golden chains she wears round her neck.
On a wood board atop the bedside table there’s a halved apple, cheese, and a small, sharp knife.
Staring at the naked woman, not really believing who she is, Tyrion walks quietly toward the bed.
Not quietly enough.
SHAE: Tywin? My lion?
She turns with a smile on her face. The smile disappears when she sees Tyrion.

Isso é reforçado ainda mais pelo fato de que nos livros Cersei quase certamente teve palavras com ela para convencê-la a fazer o que ela quer.
She followed them back inside and watched as they bundled the girl up in her father's bloody blankets. Shae, her name was Shae. They had last spoken the night before the dwarf's trial by combat, after that smiling Dornish snake offered to champion him. Shae had been asking about some jewels Tyrion had given her, and certain promises Cersei might have made, a manse in the city and a knight to marry her. The queen made it plain that the whore would have nothing of her until she told them where Sansa Stark had gone. "You were her maid. Do you expect me to believe that you knew nothing of her plans?" she had said. Shae left in tears.
