The Mystic: Bucky Barnes
Bucky wished he could take back the things he'd done under Hydra control back home. While they will not see the potential consequences for this back on Earth, for Bucky it will mean that he will have no memory of any of it.
For the next couple of weeks (until the end of the plot), Bucky will be without any memories of his time as the Winter Soldier. But, that also means he won't remember how he got on the ship or anything after his first 'death' back in 1945.
This will also mean his metal arm will disappear and he will be somewhat hampered for the next couple of weeks trying to adjust to being without a limb.
