What it says on the tin. Hydra fucks up a new healing serum, Asgard magic, wevs.

But suddenly the grim faced dead eyed asset who doesn't make a sound and knows how to dissociate through brutal punitive rape is replaced with charming people pleaser Bucky Barnes. The new younger Bucky is from before the war, so doesn't have that level of having been hardened; maybe he's even a virgin. So what now? The asset's useless for his primary purpose, so what do they do to Bucky? Do they try to re-break him, redo the process of making him the asset, in case the deaging isn't reversible? Or is it just a matter of waiting for the magic to wear off and they might as well have some fun in the mean time? Really I just want young, innocent, sunshine everyone's golden boy that nice Bucky Barnes to be confronted with the horror of seventy years of institutionalized trash.

+Rumlow is just delighted with breaking Cap's best pal Bucky
++Bucky cries bitter, hopeless tears when they tell him that it's the future and Steve's dead because he always wanted to make a move on Steve but never did
