Tony rocks Steve back and forth in his arms in a slow dance. Doing his best to ignore how slick and slippery his armour was with Steve's blood.
This was going to be their last dance.
"Don't look so sad, Tony. It's going to be alright" Steve whispers.
"It wasn't meant to end like this. We were-…" Tony buries his face in Steve's shoulder, to hide his sobs.
"Meant to ride off into the sunset? That was never going to be us, sweetheart. Don't cry. I had a good life. A happy one." Steve says. "You gave me a h-home. A purpose. A reason to continue fighting when things get hard. There is nothing in this world I am more thankful for th-than you, Tony Stark. You're my light in this world, guiding me. I love you, so much"
"I remember" Tony chokes on his tears. "I remember hearing those words somewhere before"
Steve gives him a weak laugh, "my wedding vows". With a trembling hand, Steve reaches up to wipe the tears from his face.
On his wrist, his soul-mark burns as Steve slips further away from him.
He will get over this. Stark men are made of iron.
The End
