WARNING: The following contains spoilers for WandaVision Episode 5, "On a Very Special Episode...," now streaming on Disney+.
While WandaVision has generally kept focus on its titular power couple, there's now another pair on the scene, and they're changing the show's dynamics in major ways. In their first full episode, "On a Very Special Episode...," twins Billy and Tommy prove there's more to them than meets the eye, as they're able to resist Wanda's magic and seem uncannily aware of what's going on. It's eerie to see children with this kind of awareness, but Westview's reality might actually be worse for them than it seems.
The twins start out the episode by crying, which Wanda's magic is unable to stop. Soon, they seemingly age themselves up in response to what's going on and their own goals. However, they're able to do so despite the fact Wanda doesn't want them to suddenly get older. From there, things only get weirder, as they demonstrate some awareness of their reality and situation following the death of their dog, Sparky. Standing in Agnes' yard, the twins beg Wanda to "fix the dead," which on the surface is meant to refer to Sparky. However, the way they're talking makes it sound like they mean more than just Sparky.
If the twins can see beyond Wanda's magic, then Billy and Tommy may have seen some horrifying things in Westview. An earlier episode of WandaVision, for example, indicated Westview's version of Vision actually uses the dead and destroyed body of the synthezoid. As such, Billy and Tommy may actually experience the grey, mutilated version of their father -- or have at least seen it at some point. The implications of this are then that they might have been crying as children because they could see this horrifying version of Vision and thus were aware of Wanda's ability to hide their father's horrifying appearance when talking to her later.
Billy and Tommy have also already seen some of the ugliest things the outside world has to offer. If Wanda's magic doesn't work on them, then it's unlikely she can control their memories, like she does everything else in Westview. That then means they're able to remember the attack launched against them by Director Hayward, which would absolutely be a traumatic experience for children, as well as their father's deathly appearance.
In just their first 48 hours of existence, these children have had to encounter some of the biggest questions in mortal life. It's a terrifying situation for anyone, especially for innocent children with no life experience. If Billy and Tommy are real, by the time they're teens, they'll be well on their way to being traumatized for life. In many ways, this then resembles the trauma that Wanda herself has suffered. And if she's not the one behind Westview, then Wanda might not have the control left to stop that cycle from continuing.
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.
