Guess I'm watching a different show than those here. lol That wasn't an episode; it was a jumble of scenes to hurry up and get the quest done so we can get to the big reveal. It's like all the people making these Disney+ shows - and not just Marvel - have no idea of longform story structure and just start and stop and don't balance or pace anything. It was just brooms, ouija, death, mud, Wiccan reveal, GO! That's an outline, not an episode. I honestly think it's a combination of the shrinking of writers rooms and pandemic "zoom rooms" and the limited series format with the nebulous however-many-episodes-it-takes non-mandates by producers without longform storytelling experience. It's not surprising old shows like Suits or Grey's Anatomy or Prison Break or whatever are suddenly topping the charts. It's because those showrunners knew how to run shows!
And again, I feel like either it's a deliberate actor/director/writer choice or Hahn has forgotten how to inhabit the over the top qualities of the role that made her such a standout in WandaVision, but for me, Agatha is not nearly as fun in this show as she was in WandaVision. She's just desperate and sad.
She already knew it was Wiccan - maybe from the M sigil - or at least suspected for a while, given her reaction to Rio's revelation that Teen wasn't her son the previous episode. She was playing all seductive with Rio to get the info she wanted, then as soon as she got it, smirked, went dead eyes, and turned away. Pure sociopathy in that move, which was one of the more interesting moments in the show even if it was the same moment I stopped rooting for Agatha.
Now I'm left waiting to see what Wiccan's true motivations are and if there's anyone left for me to care about at this point besides Lady Death, who I am curious if she knows Agatha was playing her or is really too in love to care. Personally, at this point, I'm hoping Death takes Agatha and returns everyone else at the end of the Road.
