And here's a post about how Wanda "dealt" with Agatha at the end of Episode 9 that I largely agree with:
"How do you feel about Wanda inflicting that horrific punishment on Agatha at the end? Perhaps she's not as noble as you want her to be.
As others have noted, she's shown self-awareness numerous times throughout the show, and even at the end, after everything, she still chooses to repeat the same sin against Agatha.
And what is Agatha supposed to do now? She's literally homeless. Where is this fictional character meant to live? She's not from Westview.
And you may retort that a SWORD prison could not hold a powerful witch, but the writers could have pulled out any other spell out of their ass to ensure Agatha was neutralized. They chose to have Wanda repeat the assault of another person's mind and body without their consent. AGAIN. No lessons learned for Wanda.
I like the interesting discussions such a character can provoke, but I always do a double-take at people defending her actions in this story. She's a selfish character. And that's ok. It makes her interesting. Especially now that her fate is in her own hands instead of others.
What she did was inexcusable though (just like what Loki did to NY was), and claiming 'she didn't fully know' is not only a flimsy excuse, but actively betrays her character arc in the story. If she didn't fully know, then what's the point of telling this story in the first place? If she only woke up in the climax of the tale, then what even was her journey?
Every time she rewrote or manipulated her reality, from episode 1 onwards, she knew where she was and what she was doing. She chose to pretend nobody was being hurt, until Agatha's mob gave her no choice but to relent.
I look forward to other more capable writers handling her character and providing us with a more tonally and thematically consistent journey."
The show ruined the earlier wonderful dynamic between Olsen and Hahn for me.
