Imagine Bucky avenging your death.
You had been killed by one of Hydras soldiers a few days ago. Bucky has been really upset and angry, of course.
While on a mission, he saw the soldier that killed you, and shot him, completely blowing his and the others cover.
"Bucky, what the hell, dude? What happened to being silent?!"
"That was for Y/N!!"
