Warning! This article contains spoilers for Agatha All Along episode 6.
Agatha All Alongepisode 6 just gave the biggest hint yet about Rio Vidal’s true identity, hidden among the major reveals about Billy Maximoff. By the time ofAgatha All Alongepisode 6’s ending, the show officially confirmed that Teen is named William Kaplan. William’s life as a young boy was outlined, from his Bar Mitzvah to his death in a car crash as the Scarlet Witch’s Hex dissipated from theending ofWandaVision.The soul of Billy Maximoff then inhabited William’s body, revealing how the character is now part of the journey down The Witches' Road.
Naturally, this episode featured many reveals about Billy and was mostly devoid ofAgatha All Along’s other cast members. Regardless, there were some hints concerning the fate of witches like Lilia and Jen, though Aubrey Plaza’s Rio Vidal was noticeably absent. This harkens back to the theories about who exactly Rio Vidal is, with oneAgatha All Alongepisode 6 Easter eggoffering the biggest clue to this mystery yet.
Agatha All Along Hints Billy Maximoff Was The Coven’s Green Witch
Billy Maximoff Was The Black Heart, Not Rio
WhenAgatha All Along’s witch covenwas formed, Lilia Calderu wrote down three names and a symbol for the four other witches who were destined to join Agatha and Billy Maximoff down The Witches' Road. This list included Lilia’s own name, Jennifer Kale, and Alice Wu-Gulliver, with the symbol being a black heart. In the show, the characters first assumed the black heart symbolized the coven’s green witch, referencing Mrs. Hart/Sharon Davis and then Rio Vidal after the former’s death.
The MCU Just Introduced A Way To Bring Back Scarlet Witch
The new trailer for Agatha All Along introduces a very exciting means to potentially bring Wanda Maximoff’s Scarlet Witch back from the dead.
It was a common theory from viewers that the black heart symbolized Rio based on her comment about having a black heart that beats for Agatha in episode 1. However,Agatha All Alongepisode 6 may have revealed that it was Billy who is the coven’s green witch. In a text from his boyfriend, Billy is told"You’re my heart,“only with the word heart showing as a black heart emoji. This implies that Billy, originally thought of as a familiar and not an official member of the coven, is actually the green witch.
Agatha All Alongepisode 6 also revealed that Lilia was the one who placed the sigil on William Kaplan to hide the fact that he will eventually become Billy Maximoff from other witches. The show already confirmed that the sigil works on the witch who cast it, explaining why Lilia - an expert in divination and future sight - wrote a black heart for Billy rather than his name, which she was bewitched not to know by the sigil. If Billy is the black heart, this could confirm a Rio Vidal theory.
If Rio Vidal Isn’t The Green Witch, Who Is She?
The most common theory about Rio Vidal is that she is the MCU’s version ofMarvel Comics' Lady Death. This was hinted at several times inAgatha All Along’s first six episodes. InAgatha All Alongepisode 4,Rio mentions that once Agatha kills the other witches, she gets their bodies. This coincided with Rio telling the coven that she once had to do her job which caused the pain of someone she loved. This was clearly in reference to her and Agatha, with the theory being that Nicholas Scratch’s death saw Rio take him as Lady Death, upsetting Agatha.
In the same episode, Agatha begs Rio"Don’t take him"when Teen is injured before stating to Agatha"That boy isn’t yours,“something she would only know for certain as Nicholas is dead. Rio’s absence inAgatha All Alongepisode 6 also came after Alice’s death, another hint that Rio is Lady Death. Finally, inAgatha All Along’s midseason trailer, Rio can be heard stating"All roads lead to me.“This could reference the fact that everyone dies eventually, leading them to Rio and reinforcing that - alongside Billy being the green witch -Agatha All Alongincludes the manifestation of Death itself.
