The first trailer for Marvel Studios' Thunderbolts* teased a possible major change for Bucky Barnes. At the end of the footage, it seems like Bucky is attacking the Thunderbolts instead of helping them. This leads me to believe that Contessa Valentina Allegra de Fontaine or someone else has reactivated his Winter Soldier condition. However, this could be merely a misdirect for the trailers, with Bucky actually helping the other Thunderbolts* in the sequence. I hope that is the case, as the MCU has gone to great lengths to move Bucky past his Winter Soldier trauma.
