On a speeding train, SHIELD Agent Ran Shen is locked in combat with the Winter Soldier when Hydra Agent Shocky Dan enters the compartment. The interloper blasts Winter Soldier as Peter and Mila Hitzig flee. Ran Shen then takes on Dan but finds him a tough customer—until he sprays a caustic chemical in the bad guy’s face. By this time Winter Soldier has recovered and he fires three bullets into Ran’s chest at point blank range; Ran releases a smoke bomb and crawls out the room. The assassin follows the trail of blood down the corridor but Ran ambushes him using Shocky Dan’s electric gauntlets. Winter Soldier is too fast for him and Ran is again at his mercy, when Bucky recalls Captain America telling him not to murder a defeated for, and he leaves.
Meanwhile, Mila Hitzig discovers that her husband has cut a deal with Hydra. They enter the dining car to discover that The Drain has manipulated everyone in the car to kill themselves. No longer needing him, The Drain hypnotizes Peter into shooting himself.
In the Soviet Union, Winter Soldier’s handlers, realizing his Bucky memories are returning, order him to abort the mission but he refuses, insisting he is all right….
