John Walker Helps Sam and Bucky Fight the Flag-Smashers [No BGM] | The Falcon and the Winter Soldier

As the Flag-Smashers get ready to leave in two trucks, Falcon sees a person inside who might be a hostage. He and Bucky chase the truck, and Bucky jumps on the first truck and meets the supposed hostage. She is actually Karli Morgenthau, the leader of the Flag-Smashers, and she attacks Bucky with super strength. Then she puts on the mask and joins the fight on the second truck’s roof. Falcon’s drone, Redwing, tries to help, but Karli destroys it. Falcon flies down and kicks Karli, but she fights back. More Flag-Smashers come from the other truck and join the battle. Sam is overpowered, but then Captain America arrives by helicopter, hits Karli with the shield, and jumps down while Lemar swings down on a line. They introduce themselves to Falcon and Bucky and realize that all the Flag-Smashers are Super Soldiers. The Flag-Smashers manage to escape and leave them behind. Sam and Bucky walk up the highway, and Bucky says they need to find out where the serum came from. What do you think
