WandaVision's series finale aired last week, with the aptly titled episode "The Series Finale," and head writer/executive producer Jac Schaeffer (Captain Marvel, Black Widow) has spoken in a new interview about how the unusual show came together. Speaking with Mashable, Schaeffer discusses the show's teasing deceptions both intentional and unintentional, and about the challenges WandaVision presented in the writing.

As Schaeffer explains, she feels a lot of the scrutiny and avalanche of fan theories the series has received about where it was heading plot-wise was "directly tied to the year-long gap in Marvel content and the fact that everybody is house-bound." For example, Schaeffer had said in another interview that she "naively" didn't expect fans to have a huge reaction to Pietro, Wanda's dead brother, making an appearance. As she said in an interview with Variety, "We didn't anticipate that the show would drop after a full year of MCU drought in the middle of a pandemic."
