Marvel Studios is mere hours away from debuting its fourth episode of WandaVision, and there is still very little known about what's actually going on in this debut Disney+ series.

The first three episodes of the MCU series have delivered on the promises of looks at Wanda and Vision's new life through the lens of American sitcom history, starting with the 1950s and progressing thus far through the 70s. Interwoven into this plot device is a storyline that displays this "unusual couple" starting off as newlyweds and becoming parents to twin boys in the span of a few days.

As expected there is a great deal of mystery surrounding the titular characters' neighbors in the town of Westview, specifically individuals like Emma Caulfield's Dottie and Kathryn Hahn's Agnes. While no specific details were revealed, Hahn has given another enticing tease regarding what to expect from the nosy, enigmatic neighbor.

KATHRYN HAHN TEASES LEVELS TO WANDAVISION

In a new interview with TVLine, WandaVision star Kathryn Hahn hints that the truth behind her character may not be what the Marvel fandom is expecting. While keeping mum regarding the rumors of who Agnes will turn out to be, Hahn indicates that the journey for Wanda and Vision's next-door neighbor is something that "people will not see coming" in the coming episodes:

“I can safely say that there are so many levels of surprises, and so many layers, that people will not see coming. I am just so excited for fans — and people that are new to this world — to go on the ride. It’s just a real, multi-level trip, and I’m so excited for people to go on the journey.”

SURPRISES ARE IN STORE FOR THE MCU SERIES

Kathryn Hahn's Agnes has served as one of the few consistencies in all three episodes of WandaVision released thus far, and it's clear that she will continue to be a mystery as the season continues.

At the end of Episode 3, "Now In Color," Agnes gave a particularly chilling look to Wanda and Vision's neighbor Herb as he thought about revealing the truth behind Westview. She stopped Herb from saying anything before cheerily riding away to tend to her macramé, giving every indication necessary that something is amiss after the first third of the season.

Rumors have pointed to Agnes turning out to be the classic Marvel villain Agatha Harkness, but it seems like it will be some time before anything official comes confirming or denying those theories. She has been heavily invested in Wanda's life since the moment Wanda and Vision arrived in Westview, and it's clear that she won't be out of their hair anytime soon.

Another layer of mystery has been added with the most recent teaser for Episode 4, which included a SWORD-organized diagram of every person currently in Westview with Wanda and Vision. Notably, Agnes had no real form of identification attached to her picture, and ideas are flowing quickly as to what this could mean in the end.

No matter what happens, Kathryn Hahn will be someone to pay close attention to as the series continues. Episode 4 of WandaVision will be available to stream on Disney+ on Friday, January 29.
