There's only one episode left in WandaVision but we still have so many questions about what could happen to the Marvel Cinematic Universe after everything that happened in the series. For instance, fans believe that mutants are coming to the MCU, thanks to Agatha Harkness' error.
In WandaVision Episode 7, it was confirmed that Agnes is actually Agatha Harkness and the character even got her own awesome theme song where she revealed everything she had done in Westview. This included sending Pietro Maximoff to Wanda in Episode 5.
But wait, is that the right Pietro? It looks more like Peter Maximoff from the X-Men Universe. Although Agatha got it right by bringing in a Quicksilver, she actually took the Quicksilver from a different universe and sent him to Wanda's house.
Many fans believe that Agatha's mistake didn't really cause too many problems since Wanda still recognized him. Nevertheless, it's a different Pietro (or Peter) and his introduction into the MCU could open the door for the rest of the X-Men to eventually show up in the universe.
The whole mutant connection was made even more interesting when it was revealed in Episode 8 that Wanda was born with her powers which would later be enhanced by the Mind Stone. With that in mind, the MCU could get even more confusing soon.
The WandaVision series finale will premiere on Disney+ on March 5.
