Flashback. The end of World War II. Paris. A landmine explodes, tossing Sgt. Nick Fury high in the air, all but killing him.
CAP (Fury): So there’s this tasty little cure-all called The Infinity Formula: helped save my life at the end of WW II…
Out of flashback. Close on Fury, half in shadow, talking but not looking at us.
Fury: Kept me the dashing young super-spy you see before you today…
Flashback. Fury injects Bucky with his last dose of The Infinity Formula, saving the Winter Soldier’s life.
CAP (Fury): Till recently, anyway.
Out of flashback. Fury steps out of the shadows and we see who he’s talking to – some of his oldest allies: Captain America, the Black Widow, Wolverine, Dum Dum Dugan. They’re all in one of Fury’s secret hideouts. Fury looks miffed.
Fury: ‘Bout time I started growing old gracefully though – been putting it off far too long. That ain’t the problem…
Fury: The problem is the Formula… I always thought it couldn’t ever be replicated. Thought Sternberg took that with him to his grave.
Hydra Secret Base. A long line of Hydra recruits are lining up for an injection. The one at the front of the line has rolled up his uniform sleeve to the shoulder. An evil Hydra doctor is injecting him. Beside them are boxes and boxes of vials, all labelled with the ∞ symbol.
Fury: Turns out I was wrong.
