WARNING: The following contains spoilers for Marvel's WandaVision Episode 3, "Now in Color," now streaming on Disney+.

WandaVision's commercials may be a fascinating, dread-inducing look inside Wanda's buried memories, and this week's entry is no different. It's a peaceful advertisement, its tropical themes selling a blue bar of Hydra Soak soap to those who want to awaken the goddess within. The name Hydra is enough to perk up the ears of fans looking for deeper connections, but this blurb might also have threaded an unusual connection to Agents of S.H.I.E.L.D.'s fourth season.

The commercial itself is typical '70s. Big hair, earthy colors and mod fashion surround the stressed-out housewife, her life bordered on all sides by disasters big and small. The unseen mind-reading narrator lures her towards a luxuriant soak in a tropical-themed wonderland all to herself, tended to by a toga-wearing servant. "When you want to get away," purrs the narrator, "but you don't want to go anywhere," use their blue soap.

The Hydra Soak soap from Wandavision episode three

Like the Strucker watch advertisement in Episode 2, it seems to point towards the trauma Wanda has suffered from Hydra's manipulations, but there's more to it than that. As the commercial changes to the housewife's pampered fantasy, it's easy for an Agents of S.H.I.E.L.D. fan to think of Tahiti, the magical tropical vacation implanted in Phil Coulson's mind to cover his memories of being painfully brought back to life via Kree technology.

While the housewife isn't actually visiting the island, the final shot of Hydra Soak in its blue, octopus-festooned wrapper harkens back to Coulson. Season 4 trapped Coulson and several of his agents inside an AI-controlled simulated reality called the Framework. Its alternate universe theme may even be comparable to whatever nightmare Wanda's slowly realizing she's trapped within, though Coulson's warped world didn't come with TV trays and a laugh track.

Coulson doesn't believe he's a S.H.I.E.L.D. agent in his new, Hydra-controlled world. The Framework's mistress, Aida, has pushed her prisoners into situations designed to woo them into submission. Coulson's forced fantasy makes him a schoolteacher, though his training manages to slip him a fondness for conspiracy theories, including one about the soap everyone's using. As it turns out, the blue soap is a Hydra creation that loads up its user mind control chemicals to make them believe their world is a magical place.

WandaVision's simple bar of soap could just be a squeaky-clean callout, but it's still a compelling one, as it could be the first clue that Coulson and his team of agents have more to do with the future of the MCU than fans were led to believe.

Written by Jac Schaeffer and directed by Matt Shakman, WandaVision stars Elizabeth Olsen as Wanda Maximoff/Scarlet Witch, Paul Bettany as Vision, Randall Park as Agent Jimmy Woo, Kat Dennings as Darcy Lewis, Teyonah Parris as Monica Rambeau and Kathryn Hahn as Agnes. New episodes air Fridays on Disney+.
