  • Bucky returns in this episode after Nightmare in Red.
  • While Captain America was held hostage in the Pentagon, Iron Man fired the antidote to the Red Skull toxin in a missile. This missile took exactly 33.125 seconds to travel 100 miles from Iron Man’s position to the Pentagon, taking it to a speed of exactly 30,188.68 miles per hour, about the speed of a meteorite. Winter Soldier was able to react to the rocket in less than a hundredth of a second and catch it.


  • In the title card, Yellowjacket and Vision are present; but they didn't appear in the episode.
