Westview through the eyes of a Witch

When Agatha Harkness feels the small spark of chaos magic, she goes to find the source. She did not expect to find some twins without a home or parents though. Her plan is to take care of them as a way to let Wanda her magic grow, with the intention to harness it for herself when it's strong enough. But when years pass, she can't help but feel like a mother figure towards the little girl.

When the twins suddenly disappear, she is convinced that they must be dead, which breaks her heart.
So she is very surprised when 8 years later, Wanda her magic appears once more, this time in the form of a powerful hex trapping an entire town. As Agatha arrives realisation fills her that Wanda does not know who she is.

She just wants to figure out what happened and make Wanda remember. If she has to pose as Agnes the nosy neighbor to do this, so be it.
When Wanda discovers who she is but there is still no recognision, Agatha is completely broken. Giving her the lie that she wants her powers for herself ensures that Wanda will take away all of Agatha's pain, one way or another.

Chapter 2 to 10 are the WandaVision episodes but through Agatha her perspective.
