Dr strange Multiverse of madness would never happen if it weren't for her.

After watching the most recent episode of Agatha all Along, I couldnt help feeling that Dr. Strang Multiverse of Madness would not have happened if it weren't for Lilia.

Let me explain. In episode 6 of Agatha all Along, there was a scene in which Lilia read William Kaplan's palm and later cast the sigil on him to hide him from witch folk.

I think this sigil was what kept Wanda from sensing him and in turn resorted to the Darkhold to ease her pain. If Lilia didn't hide him from all witches, then Wanda wouldn't have fallen and the whole movie would not have happened.

Does anyone else agree?
