We already know that S.W.O.R.D. came to Westview to investigate a missing person case but ended up discovering the Hexagon. However, WandaVision Episode 6 may have confirmed that the organization has another significant reason for sticking around and it isn't Wanda Maximoff.
In the episode We Interrupt This Program, it was revealed that Monica Rambeau is a SWORD agent who was sent by Acting Director Tyler Hayward to Westview to look into a missing person case. Here, she discovers the Hex and is sucked into the static wall. Once inside, Monica is cast into the sitcom WandaVision and becomes friends with Wanda.
Although Wanda eventually ejects her from Westview, Monica believes she can still reach out to the Avenger and convince her to take down the Hex. This appears to be Heyward's intention as well but he could have an ulterior motive: He wants to get his hands on Vision.
It has been established that Wanda stole Vision's body from SWORD and Hayward might be determined to get it back because of Vision's living will. On the other hand, his intentions might not be as noble as he likes to present. After all, he has the Cataract File, which could be a plan to weaponize Vision's body.
We don't trust Hayward and neither should anybody else. We're just hoping the truth about his plans will finally be revealed in WandaVision Episode 7.
The latest episode of WandaVision is titled All-New Halloween Spooktacular! and is now available for streaming on Disney+. The seventh episode will air on February 19.
