The Present
His blast hit him square on, causing Thanos to stagger back a few steps. That was just the distraction Tony needed to grab the gauntlet from the Titan and put it onto his armored hand to be on the safe side.
Without any warning, the soul stone teleported Tony to Vomir. It dulled down to a gray colour, no longer working. He had hoped he wouldn’t need to sacrifice someone he loved. He couldn’t lose anyone else, not again. Tony didn’t have anyone with him to sacrifice either.
Something seemed to… pull, for lack of a better word, Tony down the lone path and towards the edge of the cliff between the two tall structures at the top.
“What will you sacrifice for the soul stone?” the voice spoke in his mind.
Tears pricked the corners of his eyes. Was saving the half of the universe worth it? It better be.
“I- I’ll sacrifice” he began to break out in sobs “Morgan”
The soul stone on the gauntlet on his arm glowed a blinding yellow colour. Tony collapsed onto the ground again and held his stomach to try and keep himself together. The six infinity stones began to glow in unison, the light consuming Tony. A sudden wind began to pick up and swirl around him, the light growing even brighter. The wind turned into a violent force, and the light grew and consumed everything.
When the wind and light died down, he found himself in Wakanda again surrounded by what was left of the Avengers again. He couldn’t stop crying even as Steve and Natasha lifted him up and carried him to a medbay to make sure he was ok and not physically hurt.
“Let me go, I have to fix everything!” Tony screamed at everyone and they dropped him out of reflex. He quickly stood back up and brushed himself off. “I have to reverse this shit!”
“Tony, please wait! You don’t know what that will do to you.” Natasha and Steve exchanged a look before they took a step towards Tony.
“None of you know what I had to fucking go through on Titan and on Vomir, the things I had to do…”
“Then tell us, we just want to help you!” Steve took another step towards the mechanic.
“I had to watch my kid die in my arms, begging me to save him. I had to sacrifice my unborn daughter for the soul stone to reverse what Thanos did!” Tony’s eyes were frantic as he continued. “I’ve lost everything I’ve loved, and I have a chance to fix it along with half the universe. So you’d better stand back,”
“Tony wait-” was all the duo could get out before a sobbing Tony snapped his fingers.
