The Mysterious Voice on the Radio In 'WandaVision,' Explained

On the surface, WandaVision is a fun, cheeky sitcom about two Marvel superheroes living out their wholesome suburban fantasies. But underneath, the Disney+ show is a darker story about multiverses and trauma wrapped in a web of MCU Easter eggs. One of those A+ Easter eggs? A call-back to Ant-Man and the Wasp.

In the '60s-inspired second episode, the fourth wall is momentarily broken when Wanda (Elizabeth Olsen) hears a voice on the radio repeatedly asking her, "Who did this to you?" The strange occurrence isn't addressed again in the episode, but fans quickly matched the voice to Agent Jimmy Woo (Randall Park).

Woo, of course, was the federal agent assigned to keep tabs on Scott Lang (Paul Rudd) during his mandated house arrest in the Ant-Man sequel. Less villain and more bumbling pesky adversary slash youth pastor (like, actually), Woo can't seem to figure out how Lang keeps evading his clutches (hint: he's a superhero) or how he does those card tricks. Woo hasn't been seen again in the MCU even though Ant-Wan and the Wasp (Evangeline Lilly) were included in the good guy army that took down Thanos in Avengers: Endgame.

Woo isn't the only tertiary MCU character set to reprise his role in WandaVision. Kat Dennings, known as Darcy in the Thor films, is also confirmed to appear in the new show.

Is Woo working to help Wanda? Is he just keeping tabs on her as he did with Scott? (Remember: Wanda's technically a fugitive after Captain America: Civil War, though it's not clear what happened to the Sokovia Accords after the Snap.) Is Woo a part of S.W.O.R.D.?

Episode 4

WandaVision finally gave viewers many answers in its fourth episode, zooming out of Wanda's alternate world to show how her actions are affecting everyone else. One of those answers? That it was, in fact, Agent Jimmy Woo (who seems to have learned some of Scott Lang's card tricks) on the other end of the radio receiver.

The episode shows how Woo, still an FBI agent, was one of the first to suspect that something fishier was at play when it came to Wanda's mysterious town. He contacts S.W.O.R.D. for help, but after things go awry and Agent Monica Rambeau (Teyonah Parris) disappears, he joins in on the rescue efforts/investigations into Wanda's "show." At one point, he and Darcy try to hack into Wanda's world through her radio and we see Woo speaking the lines Wanda heard in episode 4.

Park's continued hilarious portrayal of the character was an immediate crowd-pleaser, with Twitter lighting up with some of his best moments from the episode.

While viewers may be surprised to realize Woo plays such a major part in the show considering his limited role in the MCU thus far, fans of the comics shouldn't be phased. Per Inverse, Agent Jimmy Woo was actually at the center of Atlas Comics' Yellow Claw series, a Marvel predecessor that debuted in 1956. According to Inverse, Woo was one of the first Asian-Americans heroes in comics and was more "straight and serious with swagger and suave like James Bond."

Inverse also reports that Woo's character continued on in the Marvel Comics, working alongside S.H.I.E.L.D. agent Nick Fury. Woo eventually became the leader of the "Agents of Atlas."

Could Woo's presence in WandaVision be queueing up a future spin-off where he leads an Avengers-like group of superheroes?

Studio head Kevin Feige did previously tell Variety that he was using Disney+ as a way of "growing and expanding" the world and that they plan to "further explore characters," so there is always a chance.
