Agatha All Along‘s third episode, “Through Many Miles / Of Tricks and Trials,” mentioned a major name within the franchise: Mephisto, an extradimensional demon and ruler of Hell. According to Comicbook, Mephisto is mentioned when the coven takes in their first trial of the Witches’ Road, where they get poisoned by magic wine, and it’s up to Jennifer to brew up an antidote. There will be more trials along that group will have to complete that wil help in improving both their powers and characters.
It was Jennifer Kale, played by Sasheer Zamata (Home Economics), who spoke to Teen, played by Joe Locke (Heartstopper) during the journey. She tells him the rumor surrounding Agatha’s past, about how she traded her son in order to obtain the dark hold and she subtly drops hints that he might be a demon or even an agent of Mephisto.
According to Comicbook, this is not the only easter egg in the series; due to Marvel lore, Jennifer Kale is a powerful sorceress and ally to supernatural heroes such as Man-Thing. The character is the descendant of Noble Kale, who has a connection with not just Mephsito, to whom he sold his soul, but also Ghost Rider, which is represented by the medallion of power that Noble carried and held a portion of the spirit of vengeance transforming him into the first Ghost Rider.
The easter eggs might just be the beginning of a larger story involving Mephisto and his agents. There are currently three episodes of the mystical drama series available to stream on Disney+, with future episodes premiering every Tuesday as the series delves deeper into the series plot and the story behind the characters. Whether Mephisto or Ghost Rider will make a cameo in the mystical drama has yet to be confirmed, but this will surely add more anticipation to the viewers, leaving them wanting more.
