Who dies
They got Stark involved. They even somehow found Thor- Pietro recognised his depression, it was different to Wanda's, but he knew he'd been struggling.
The plan was quick, simple.
Get the stones.
Come back.
Snap.
Simple.
Cap, Tony, Bruce and Scott went to New York; Thor and Nat went to Asgard; Nebula and Rhodey went to Morag. That left the twins to go to Vormir.
They got up onto the platform, adjusting their suits and placing their particles.
"See you in a minute," Nat smirked.
They pushed down on the particles, sending them shooting through time and space.
It was such an odd feeling, Pietro pondered, shooting through the fabric of the universe was a lot like how it felt to run at the speed of light. It felt strange but exhilarating. Like you weren't meant to do this, but at the same time it was your destiny.
They said goodbye to Rhodes and Nebula at Morag, and got into their ship.
It felt great flying through space, lighting fast, zooming along.
"A long way from Novi Grad," Wanda said, grinning.
Pietro let out a laugh at seeing his sister so happy. She hadn't felt like this in a long time, he knew.
When they arrived, they saw nothing but a vast mountain, and Wanda's eyes glowed red.
"This way," she said after a second, leading them up the mountain.
Half way up, they were stopped by a hooded figure. Wanda drew up her scarlet power, and Pietro readied his gun.
"Welcome, Wanda, daughter of Oleg," the figure spoke, "Pietro, son of Irina."
"Who are you?" Pietro asked warily.
"Consider me a guide," he said, "to you and all who seek the Soul Stone"
"Oh, good," Wanda said, "tell us where it is and we'll be on our way."
"Ah, lieschen. If only it were that easy." He led them to the edge of a cliff.
Pietro gazed down, a sinking feel in his stomach. He almost knew what this was.
"The stone's down there?" He asked, guessing the answer.
"For one of you. For the other, in order to take the stone, you must lose that which you love. An everlasting exchange. A soul for a soul."
Pietro sat silently as Wanda kept trying to find a loophole.
He knew what he had to do. He'd made peace with it.
"Wanda," he interrupted her mid sentence, "I think we both know there is no way out of this. I love you."
Wanda looked at him, "absolutely not. You have people you love to get back. I have already lost the one I love. Nobody would loose if I die."
The sentence was just sad, and Pietro looked at his sister's face.
"I would," he said.
"And I would loose if you died," she retaliated.
"Wanda, please. You have a family. The Bartons love you as their own. They dont love me like that."
"Bullshit. They love you."
"And Sam," Pietro continued as if she hadn't spoken, "would never forgive me if I killed his little sister."
"Well he's just gonna have to live with it," she said, running towards the edge of the cliff.
She jumped as if in slow motion, before Pietro caught her with his grappling hook. He fell, only to be caught by his sister's hand.
"Let me go," he said, "it's okay."
But she didn't.
Instead she used her powers to pull him up.
"I love you," she said, before falling to her death.
Her death.
Wanda Maximoff. His twin. The one who was always with him.
Dead.
He had the stone now, but that didn't matter.
Wanda was dead.
He held the stone tightly, and let the tears fall.
Death doesn't discriminate
He should have died
Between the sinners
He was a sinner
And the saints
She was a saint.
It takes
She was taken
And it takes
She was gone
And it takes
Wanda Maximoff is dead.
