WandaVision is chock-full of Marvel Easter eggs, but a subtle reveal in the fifth episode hinted at further expansion of the Cinematic Universe. As Darcy Lewis, Jimmy Woo, and Monica Rambeau try to find a safe way into Westview Monica reveals she knows an aerospace engineer who'd be "up for the challenge." The moment is given deliberate focus as Monica texts her friend, it's clearly a hint at what's to come, and many fans speculate they know exactly who she's talking about: Reed Richards from the Fantastic Four.
Although there was little indication of the Fantastic Four's involvement in Wandavision previously, clever viewers have noted a small connection to Ben Grimm came up in the premiere episode's closing credits. As far as aerospace engineers go, Reed is considered the standout choice in the Marvel comic book world. Plus, his friendship with Monica can be traced back to 1989's Captain Marvel #1, as pointed out by Nerdist. You might assume Carol Danvers would be up for this job, but judging by the way Monica reacts to her name, there's clearly some bad blood there.
Fans of the Fantastic Four have been eagerly awaiting the family's inclusion in the MCU, since Marvel's CCO Kevin Feige confirmed a new movie is on its way with director Jon Watts. There have been few updates since then, but just last week, Elizabeth Olsen teased a major cameo to come in the show that she's "really excited" for. Could it really be Reed? And if it is, who will play him? For what it's worth, theorists on Twitter picked John Krasinski as their Mr. Fantastic long before Marvel even confirmed a film. We'll be waiting on the edge of our seat as drama continues to unfold in Westview.
