Towards the end of the WandaVision spin-off's opener, Rio attacks Agatha (Kathryn Hahn) at her home in Westview, but the latter wiggles her way out of the brawl by persuading Rio to wait and fight her when she's regained her powers – and is therefore a worthier opponent.

“Heartstopper” actor Joe Locke, whose “Agatha All Along” character is billed as Teen but is rumored to be Wanda Maximoff’s (Elizabeth Olsen) multiverse son, confirmed the queerness of the show.

Aubrey Plaza is making her MCU debut in Agatha All Along, but so far her character Rio Vidal is shrouded in mystery. Naturally, that promotes fan theories – and Plaza herself has fanned the speculation flames by addressing the enigma that is her character.
