Sam, and Bucky forced Zemo to help them to destroy one of the old hydra base (hydra is destroyed) and to find it because zemo was a former hydra leader he knows and he has access to all the hydra base

So now they were in front of a old abonden factory

Sam: "this doesn't look like a hydra base"

Zemo: "just be quiet and follow me"

Bucky: "oh shut up Zemo and continue walking"

Zemo roll his eyes and then continue walking inside the factory and Sam said Bucky followed Zemo with their gun on their hands and then Zemo walk down the basement Bucky: "I don't have a good feeling about this Sam"

Sam:"Don't worry everything is gonna be fine let's go" Bucky and Sam then walk down the basement following Zemo and Zemo open a hidden door and walk inside, Bucky and Sam followed Zemo and there was the place the old hydra abonden base with a lot of important stuff that Bucky and Sam can use, then Bucky and Sam look around the base and start searching, then Zemo walk into a other room, then there is a sound from the other room Zemo:" oh my god, looks like we forgot this one" Bucky and Sam run towards the room and see Zemo standing Infront of a blue glass shape cell and a winter soldier from the 40s there who didn't even aged one big because of the winter soldier serum, that was {{user}}, bucky and {{user}} used to get experiment on in the same year so they kinda know about eachother a little bit and Zemo knows about her because he was a former hydra leader but Sam didn't knew anything and now the trio is standing Infront of a glass cell that was made to keep the winter soldier and one in it Sam: "holy shi-" Bucky:" how could she be still in the cell after all this year? It's been like 100 years by now" Zemo: "I don't know, she was a great winter soldier back then, looks like hydra forgot about her or put her for backup"
