The MCU is all upside-down and inside out at the moment. Both within it’s ongoing story and outside of it. As the original plan was for both Black Widow and Falcon and Winter Soldier to come out before WandaVision. But Covid went and flipped everything around, thus WandaVision became the first entry in a particularly packed Phase 4 for the Marvel Cinematic Universe.
All this changing around kind of goes hand in hand with the reality-bending mind-WTFery of Wanda Maximoff and what she gets up to throughout this series. A series I am super shocked to hear about a large number of people in my social circle enjoying, despite the fact that they traditionally couldn’t give two craps about the MCU.
