Spoilers for WandaVision!
On February 19th we learned the identity of Agnes. Her true name?
Agatha Harkness.
Many fans believe she is a secondary villain that is helping hide the real bad guy until the finale. Like others I believe Mephesto is that villain. So how could he fit in and has his connection to Agnas been unearthed by Paul Beatnys hint about the best reveal yet?
As a fan and writer, Here's my theory of what story plots are in store and the list of facts, leaks, and opposite actions inspired from the lore which might support it.
You now know AGNES IS the comic character AGATHA HEARTLESS.
Like the comics, She could be an accomplice to Mephesto in the MCU.
Mephesto who we know from comic lore wants to rewrite reality. But our Mephesto is different from the lore as he seeks to use the Villain Dormammu Darkness power that was shown in the first Dr. Strange film. Despite Dr. Stranges attempt to prevent Dormammu from entering the MCU universe, my evidence supports an idea that has Dormomo being brought back but only if reality is rewritten from within Earth itself. Dr. Strange said to Dormammu that he could never come back to THAT earth. So what if Dormammu changed the earth so it wasn't it anymore. If reality changed in the Hex, his pact with Strange is void.
Here's how:
In the comics, Agatha has a son. Named Scratch, he is a known villain.
I believe he is the unknown character Paul Bettany hints at. Paul says he knows the individual but hasn't been able to work with him in his desired way. If you research Paul's past interviews one of his heroes is Robert De Nero. I think the character Scratch is played by Robert de Nero. I believe that we'll find another important character and that it's Scratch's De Nero who helps save the day.
Where has Scratch been? I believe he is trapped in Westview as the Mayor under Mephistos control. Inspired by the comics, instead of a villian he could become an antihero and he could be the key to saving Westview. Wanda, Monica, alongside Darcy could discover by accident that like his Mom, he has magical abilities that can save Vision from being destroyed beyond the Hex barrier. I would believe his rescue by Wanda's team would be next week's cliff hanger.
The finale would end with Scratch able to restore the memories and life force of Vision but results in him being killed by Mephesto who is the Director of SWORD agent in disguise.
Mephesto would reveal to Agatha that Scratch was going to be killed anyway as a sacrifice to enable Dormomoe to enter the MCU universe because the Hex is a conduit powered by both Scratch, Wanda's grief and Agatha's manipulation of Wanda.
The conduit was failing because SWORD finds out from Agent Woo w/ FBI who needs help understanding what is wrong with Westview.
As a result Mephesto has to adjust plans when Monica enters the Hex and starts to unravel things. When Mephesto takes control of the SWORD agent he manipulates reality to convince authorities to places blame on the actually innocent Director. Like what Loki pulled on Thor, Mephesto was always a trickster and intended on using vision as a gateway for Dormammu because to rewrite reality he needed a combination of souls, Visions dead body without its infinity stone and enough magic essence from Wanda because her powers came from the infinity Mind Stone that Loki once used.
Agatha didn't know her son Scratch was secretly trapped by Mephesto. As Mephesto was having Scratches' powers drained to power the gateway that Vision was meant to be. Vision couldn't power it himself because he was dead though Mephesto needed his body to be reanimated to bring Dormomo back in as the gateway required advanced tech only found on Earth or from living celestial. Agatha discovers his deception too late and through her grief of her son's passing helps Vision, Darcy, Wanda, and Monica thwart Mephistos plans.
She manipulates the portal which saves Vision from dying again. She walks through the portal as the gate would stay open without a powered individual to go in it.. She says that her being in the portal is only a temporary fix and that the group needs to find Dr Strange and others to prevent what was happening in Westview from happening everywhere else on earth. Only with a team of masters of mystical & scientific knowledge can they prevent it from rupturing reality and destroying all life. When Wanda asks why she was doing this for them she simply says: For the children.
Wanda & Vision would then be allowed to live on SWORD HQ Base where Monica, Darcy and Woo oversee events. The finale ends with Wanda & Vision arriving at their new home getting ready to unpack talking about having a family. Only they hear a thump and are stunned when Billy and Tommy, now teenagers, are shocked when their parents open closed doors to their bedrooms.
How this sets up MCU & Disney Plus:
Dr. Strange 2nd movie would have him be summoned by SWORD to put a end to the Wandavision plot. However events get out of control and he needs to save the multiverse. Fox and Sony film universes would collide to create that multiverse of madness. Fantastic Four enters the MCU and can't return home bc of the battle at the end of the film.
Like the Fantastic Four, the Spider-man 3 film could have Peter Parker meet other Spider-men during the events of Dr. Strange who help distract Jameson by convincing him they are Spider-man while Peter is in a meeting with JJ.
JJ retracts his statement and Dr. Strange sends the other spidermen home with a device designed by Shuri, Bruce Banner, Riri, and Reed Richards. Jessica Drew aka Spiderwoman would then appear at Dr. Stranges request to help mentor Peter learn about living within the Spider Verse.
For the Ant Man 3 film, Wandavision would address the reality altering effects other dimensions have on humans. The pym family works to find a cure for Westview residents. Joining them is the assistance of a San Francisco teenager named Riri who got an internship with Pym Particles. The company is now able to operate without the FBI hunting them as the world Court states that without Pyms invention and Scott Lang in the van, the Avengers wouldn't have been able to save the world in the Endgame film.
But after the battle of Dr. Strange 2 film, the Pyms work with the Fantastic Four to help treat citizens all over the world who start developing mutant powers thanks to that reactivated X gene that was not activated from terrigen but instead from the combination of the events in the Eternals film, the Wandavision TV show, & the first Dr. Strange movie with Dormammu.
The Eternals film would show how the experimentation on humans led to a X gene activated on Neanderthal terrens.
The Eternals deactivated the gene due to rebellion from their creation they called Inhumans.
The only way to activate the gene and receive powers prior to Phase 4, was for all human Neanderthal descendants who were exposed to terrigen. Descendants that had the deactivated gene lived, while those without it died from the Terrigen mist exposure. Except the Madness of the Multiverse movie made all terrigen in the universe be destroyed and the x gene was then activated in other ways as a result of messing with Time Space continuum.
The Captain Marvel 2 film would have Monica Rambo become Agent Spectrum who works for SWORD as the new Director due to the PR fallout of Mephistos actions when he tricked the world into thinking the director was evil. Spectrum and Captain Marvel would then focus on the impending events or after effects Disney would bring with the Skrull Invasion TV series.
Loki tv series would setup the events that lead up to Westview.
Armor wars would have Riri Williams debut as Iron heart following her other appearances.
