To cap off the issue, Zemo gets his hands on an old film reel labeled “Winter Soldier”, which appears to be some sort of video documentation about what happened to Buck.
This makes some sense as Zemo’s father has pretty much stood on the “I killed Bucky” claim to fame since 1963, so now Zemo the younger is looking to understand his fathers failure, as well as manipulate the situation to his own benefit.
A very Zemo thing to do.
