Steve saw Bucky die. Saw him fall from the train decades and a lifetime ago. He grieved for him.
Then Steve wakes; 70 years in the future. It feels like a dream.
Bucky is alive again, but doesn't know him.
Bucky remembers him, but runs and hides.
Bucky is found, but his brainwashing takes over.
Bucky chooses cryo, while they try to help him.
Then it is war, fighting side-by-side together once more; a dream come true.
Bucky alive has always been like a dream, fading in and out of focus.
A snap of golden fingers, and Steve wakes.
Alone.
