Winter Soldier is the 21nd episode of season two of The Avengers: Earth's Mightiest Heroes and the 47th of the overall series.
No one knows who the Winter Soldier is or how he came to be. But one thing is for certain, he's the Red Skull's top gun. So why did he disobey orders and save Captain America's life? What is he truly after? 
- The opening scene shows 1945 as the year when Captain America and Bucky attacked Red Skull's fortress in Norway. However, in Living Legend, Iron Man says to the awakend Captain America:"This isn't 1943, Captain.", implying that the battle happened in 1943.
"Bucky?" - Captain America
"Who's Bucky?" - Winter Soldier.
