Peggy Carter has become something of a focal point for Marvel’s What If...? She might be the character most affected by the multiverse, often for the better. After all, Hayley Atwell’s super spy was the first character remixed in What If Season 1, going from Steve Rogers’ spunky romantic foil to a super soldier in her own right. Now known as Captain Carter, Peggy is the de facto face of What If. She’s popped up in a handful of episodes to demonstrate just how different the universe might have been if she were the first Avenger. Now, thanks to a minor detail in Season 2, we know just how impactful her role as Captain Carter is across the MCU.
