Como Magneto sabia que a Mystique injetou o metal no corpo de Laurio?

Embora não seja tão óbvio no filme, no roteiro original, Laurio entrou na câmara de escaneamento (e depois no celular) com um enorme sorriso estúpido em seu rosto e uma arrogância em seu passo . Todos ao seu redor colocam 1 + 1 juntos e imediatamente identificam que ele teve sorte na noite passada.

Desde que ele tem quantidades enormes de ferro coloidal em sua corrente sanguínea, Eric então descobre o que realmente aconteceu com o Sr. Laurio na noite anterior; Uma mulher dormiu com ele e depois (sem saber) o injetou com metal. Não é difícil descobrir quem pode ser essa mulher.

No filme, eles mudaram um pouco a sequência de eventos, tendo Magneto dormindo até Laurio entrar na câmara e depois acordá-lo detectando o metal. Embora eles tenham mudado a sequência de eventos, eles obviamente ainda mantinham a linha de não confiar em uma mulher bonita porque, diabos, é uma boa frase, além de ser geralmente um bom conselho.

A partir do script do filme

INT. PLASTIC PRISON - SECURITY CHECKPOINT - DAY TWO GUARDS stand in the room by the door to the catwalk. LAURIO enters carrying a tray of food.

GUARD 1: What's that on your face, Mitch?

LAURIO: Sa-tisfaction.

The Guard grimaces at the thought of it, and opens the door.

GUARD 1: You're clear.

INT. PLASTIC PRISON - SAME TIME

Magneto angrily paces back and forth -- thinking about Charles. He stops and looks at Laurio... curiously.

LAURIO (O.S.): Have a nice sleep, Lensherr?

Laurio enters and puts the food on a table. His smile becomes a scowl when he sees Magneto staring at him.

MAGNETO: There's something different about you,

Na novela do filme, eles escolheram um meio-termo, tendo Magneto visto o sorriso de Laurio enfrente quando ele acordou :

Mitchell Laurio was whistling as he came on shift. He couldn’t remember many of the details of what had happened in the ladies’ can, but he’d never felt better in his life than he had after it was done. Just the memory of Grace’s farewell kisses was enough to stir his blood and put a spring in his step, and the fact that she’d left a whispered promise to meet him again tonight made him wish as he never had before for the day to end.

The guard at the final checkpoint was the latest to offer comment: “Mitchell Laurio, what is that on your face, man?

“Sa-tis- fac-tion!”

...

Eric Lehnsherr was asleep until Laurio stepped over the threshold. Then, just like that, he came completely awake with a rush he hadn’t felt since his capture.

“Sweet dreams, Lehnsherr?” asked Laurio, his mockery plain. Just because he’d had the best night of his life didn’t mean he was going to pass on the morning beating. The one gave him just as much pleasure as the other.

Laurio set the tray on the table. Lehnsherr hadn’t moved, beyond sitting up on the bed. There was something different about his expression, though, like there was a big joke being played here that only he was privy to. But at the same time, there was a predatory cast to his eyes that made Laurio suddenly wish the internal monitors were active and that he were somewhere else.

As was usual for him when he felt ill at ease or threatened, Laurio got aggressive. This time, he decided, he wasn’t going to stop until the old man begged him.

“There’s something different about you, Mr. Laurio,” Lehnsherr said with a slight question to his voice, as if he couldn’t quite credit what he saw.

    

Tenho certeza de que Magneto pode sentir o metal magnetizável da mesma forma que os pássaros podem, um pouco. É um sexto sentido exibido em muitos animais.
