Bucky Barnes, day 14
The final return of Bucky’s memories was instantaneous in the comics, a result of Steve’s wish on a magical artifact called the Cosmic Cube. Bucky immediately withdrew from Steve and disappeared for some time. They only met again once – teaming up together mid-battle on a runaway rocket – before Steve’s death at the end of the first Civil War.
