He was dead. Of course he was.
But he had left something behind.
Vision asked time and time again what changed her, impacted so deeply after her brother's untimely demise.
She hadn't known, really, until four years later. Memories of Ultron's Sokovia battle had always been blurred, colors and the sound of metal forming a bloodied picture of battle.
The moments during Pietro's death were filled with red and the glare of winter sun in her eyes, but she remembered a space–a slot in time, where mind had disconnected from body. There her brother was, mingling at the edges of her brain as he hit ground in a heap of blue fabric and blood.
Some day, Wanda realized what it was.
A thing so wonderful that it could not be contained in her own mind and instead went to her heart. She couldn't describe what it was, what emotions it could be categorized under.
She remembers that the sun was setting. The stars are just over the horizon. Stars make her think of space, where her body floats and vacuums brush against her skin. The earth is in the distance, sun eclipsing behind the form of the blue and green planet. She feels as if the entire expanse of the Milky way has been shoved in her head through her ears.
She closes her eyes...
Everything is too much, so she cries. Wanda doesn't cry over his death, her buried parents, the fact that one day her makeshift little team of humans in metal suits aren't going to be there to hold her hand. No, she cries over the universe. She cries over heaven.
Wanda thinks that heaven will maybe feel a little like filling the inside of her brain with all the knowledge of everything. She thinks it might feel like the universe.
And she cries, because she can't feel like this forever. She only gets a few seconds like this, because her mind is so small, so weak.
Wanda can see her brother, bullet holes in his chest. She's inside his skull as he dies, as he becomes nothing but a rotted corpse. She sees his mind as it slingshots into space, where he stops on her.
She has no helmet. But here, in the vacuum of space is where she can breathe.
