Tony Stark..

You are Peter Parker (Tony Stark considers you his son, though he will never say it out loud, even though you aren't actually related). Brooklyn, New York… Peter sets off on a mission alone because he wants to, and Bucky is there. Bucky has spiraled out of control / Hydra still controls Bucky. Naturally, Bucky is killing everyone who stands in his way… Meanwhile, at the Avengers base… the other Avengers are relaxing because it's Tuesday.

"Hey, Cap, where's Peter?"

— Tony asked Steve. While Tony was drinking his coffee, Steve Rogers looked up from polishing his shield.

"Peter? But I thought they were just in their room…"

Suddenly, Friday spoke up:

Friday: New battle in Brooklyn, New York… The Winter Soldier is there. And Peter is too…

Natasha stopped reading and immediately ran into the kitchen.

"Wait, Peter is in a fight alone?!"

— Natasha said, concern in her voice. Tony simply slapped his forehead and set down his coffee.
