a broke machine just blowin' steam (слэш)

Given a choice between Tony Stark and Steve Rogers, Tony is pretty sure most worlds would choose him to search for a misplaced Winter Soldier. After all: look at what Rogers did to their own for his Bucky's sake.
What he fails to account for is the wormhole's destination, which happens to be the middle of WWII. It's a nightmare come to life... for the Winter Soldier as well as Tony Stark.

Tony's life doesn't flash before his eyes or anything like that. He's almost died too many times to still have that nonsense going on. He has a split second to think: well, of course, and also, fuck, I promised Barnes I'd get him home. Of course it would happen like this. Ever since Rogers walked into his life, Tony has been destined to be killed by him because of Barnes.
The shield is almost instantly caught in a metal hand. The Soldier twists all of Sergeant Barnes on the axis of his shoulder, landing him roughly on the floor face down, and slices the shield down. It ricochets off the cement floor and sticks to the roof of the hangar with the eerie sound of shearing metal.
