Gamora, the Destroyer of Thanos, was meant to have been introduced in her own chapter in season 1, in which she teamed up with Iron man. It had to be pushed to season 2 due to Covid-19 related restrictions.
This is the only episode in the first season to feature a post-credit scene.
Captain Carter's costume's color scheme reflects that of the one Steve wore in Captain America: The Winter Soldier (2014).
The music that plays during the opening sequence is reused from around 9 mins into What If... Captain Carter Were the First Avenger? (2021).
