Inspired by the prompt above. In attempting to make a second asset, Hydra somehow grabs a Bucky from another dimension, except their aim wasn't great and they got one who wasn't the asset yet. Instead of a second murder machine, they get twenty year old Bucky who's horrified and defiant but really no match for the Asset.

+Bucky being forced to watch his older self be raped and do nothing to stop it, as an object lesson after Bucky tries to escape: if we can do this to him, how long are you going to last?

++Bucky being separated from the asset and used by some hydra goon or official who seems like a better alternative at first, because they're interested in grooming a compliant pet instead of brutal violence

+++the two Buckys resent one another, for being weak, for not fighting back, for letting it happen, for being treated better than the other, for being used to punish the other, anything
