The sounds of guns firing from the distance rang in Wanda's ears, a sound she had grown accustomed to over the years. But something about this wave of bullets felt different, more brutal, more unforgiving. Something was wrong, very wrong.
A quick scan of all the minds in the battlefield confirmed the worst nightmare that she never dared to dream about, a thought so terrifying the witch tucked it far in the back of her mind. Amongst all the terrified fears, the screams for loved ones and cries of the injured, she found the way-to-fast-for-her-to-read thoughts of her twin. They slowed down to halt, and so did he. Pietro was probably several miles away from her, but his stupid snarky catch phrase was clear as day in her mind.
"You didn't see that coming"
Then nothing...
She couldn't see...
She couldn't hear...
She couldn't breathe...
All of Wanda's senses completely shut down and for a fraction of a second, time stopped.
She didn't care about the core any more, Ultron, the avengers, Sokovia, NOTHING. Pietro was gone.
For the first time in her life Wanda Maximoff was completely alone in the world.
