Darcy Lewis returns to the MCU in WandaVision and actress Kat Dennings has confirmed she is working on “things” for Marvel, which means the MCU can fix a mistake they made by leaving Jane Foster out of Avengers: Endgame. Darcy, aka Dr. Lewis, joined the SWORD and FBI agents stationed outside Scarlet Witch’s hexagonal barrier, which Darcy dubbed “the hex.” Crucially, Darcy was recruited by SWORD for her expertise in astrophysics, having pursued a doctorate in the field following her internship with Jane Foster (Natalie Portman) in Thor.
When she was introduced to the MCU, Jane Foster was known as one of the foremost astrophysicists on Earth, yet she was mysteriously absent from the MCU after Thor: The Dark World – even when she would have been the perfect character in the MCU to study and explain the multiverse timeline, alternate branches, and the Quantum Realm. Instead, characters like Tony Stark and Bruce Banner – who are brilliant engineers, physicists, and biochemists – took over the roles of explaining the multiverse when astrophysicist Jane Foster would have been more suited to the job.
Darcy’s return in WandaVision and continued MCU presence sets up the possibility for her character to become a spiritual successor to Jane Foster, who will also return to the MCU, but in a very different capacity. When Jane becomes Lady Thor, Darcy can take over as the universe’s leading astrophysicist and prove herself a worthy mortal asset to the superpowered beings who, frankly, pull too much information out of thin air rather than consulting experts. Particularly when the stakes of events like Endgame involve the fate of “normal” humans who rarely have a say in what happens to them beyond battle combatants. With her emergence in WandaVision as a prominent astrophysicist to rival Jane Foster, the MCU shows how far Darcy has come since Thor and teases how far she could go, which would redress the injustice of Foster being removed from Endgame where she should have played a key role.
In the first Thor film, Darcy Lewis was introduced to the MCU as Jane Foster’s intern, even though Jane Foster is an astrophysicist and Darcy was a political science major at the time. The joke was that Darcy was the only applicant for the position, despite her lack of experience in astrophysics. By the time Darcy appeared in Thor 2, it was clear she had taken an interest in the field – no doubt inspired by the brilliance and passion of her mentor and friend, Jane Foster. Beyond that, she’s become a bonafide expert in a seriously narrow field. Her WandaVision role has already established her as the key to SWORD understanding what’s happening to Wanda and why and even more importantly, what impact it could have on the fabric of reality. Given that the MCU has a major multiverse arc coming up, Darcy’s role should be expanded to continue to make her the font of knowledge.
It’s currently unknown whether Darcy will return in an MCU film, television show, or something else. As Dennings told Extra, “There are some things I’ve done for Marvel that are coming.” Other possibilities include video games or theme park rides (Disney is adding an Avengers-themed area in Disney’s California Adventure), but Dennings mostly ruled out the potential for Darcy to appear in Thor: Love and Thunder. Fundamentally, if Dr. Darcy Lewis could somehow continue her WandaVision position as an advisor to SWORD and the Avengers, it would fill the void left by Jane Foster and return an important voice to the superhero dynamic.
