How to Watch Marvel's 'Agatha All Along' Tonight

Who's been messing up everything? It's been Agatha all along...

More than three years have passed since Kathryn Hahn's Agatha Harkness revealed she hexed the Scarlet Witch and killed Sparky in WandaVision. The villain spent the entire season tricking Wanda Maximoff, trapping her in the town of Westview, New Jersey, but she then wound up defeated. Ensnared in a curse cast by Wanda herself, Agatha -- now known as Agnes -- was left without her witch powers or access to the Darkhold. 

Agatha All Along picks up after the events of WandaVision and focuses on the centuries-old witch who's bound by the Scarlet Witch's spell. A teen comes along and helps free her, and the pair form a ragtag coven and set off for the Witches' Road. Whether they make it all the way through to gain their desires is the question. 

The show features Hahn with Joe Locke as Teen, Aubrey Plaza as Agatha's frenemy Rio Vidal, Patti LuPone as Lilia Calderu, Sasheer Zamata as the witch Jennifer Kale, Alice Wu-Gulliver as Ali Ahn and Mrs. Hart/Sharon Davis played by Debra Jo Rupp. Tag along on the road trip by finding out when to stream the newest Marvel TV series.
