WARNING: The following contains spoilers for WandaVision episode 4, "We Interrupt This Program," now streaming on Disney+.

The latest poster for Marvel's WandaVision once again contains a hidden detail that may point to a further mystery.

Marvel Studios released the latest poster for the Disney+ series following the release of episode 4. Marvel has been regularly dropping posters for the show after each new episode, and this one brings together all of the characters seen in "We Interrupt This Program." Surprisingly, though, the group is joined by a shadowy figure we may have seen before.

Along with Wanda and Vision, the poster shows Monica Rambeau, aka Geraldine, in her S.W.O.R.D. uniform. FBI agent Jimmy Woo and scientist Dr. Darcy Lewis are also highlighted. The show brought back the two characters, last seen in 2018's Ant-Man and the Wasp and 2013's Thor: The Dark World, respectively. Westview resident Agnes is also present, once again hinting that she might play a larger role in the unfolding mystery. And in the background, various S.W.O.R.D. agents can be seen at the basecamp outside of Westview that the episode finally explored. But among the familiar faces, Marvel seems to have hidden someone else.

Above Woo and to the right of Agnes, there appears to be someone in a hazmat suit similar to the "Beekeeper" character who emerged from the sewers in episode 2. Last week's episode finally revealed this figure to be Agent Franklin, a S.W.O.R.D. member who traveled underground into Westview to explore the anomaly. Before exiting, Franklin encountered a swarm of bees that followed them to the surface just in time to be spotted by Wanda and Vision. In the episode, Wanda reverses time to prevent her and Vision from seeing Franklin emerge, but we don't yet know what happened to the agent.

It's not clear if the figure is Franklin, which could simply be read as a nod to one more of the elements present in the recent episode. But if that were the case, it doesn't make sense that the character would be so obscured; the agents in the background are even more defined than the mystery figure, who is almost imperceptible at first glance. Add given the fact that the mystery character is positioned and proportioned as prominently as the main cast, and it seems clear that viewers are meant to regard this person as important—once they spot them, that is.
