'Agatha' episode 3 scatters a lot of little clues about the company on the Road. Other than introducing the first trial on the Road, the Wizard of Oz theme takes a backseat. Good choice, as now we can follow each character's backstory without needing to forcibly connect them with their Oz doubles (oh, really?).
Let's start with Agatha. She becomes very unlikable as her cowardice and selfishness amp up in this episode. She is either lying about having walked the Road before, and she's just winging it, or judging by her behaviour on this current journey, she might have survived the last one at the expense of her travelling companions back then. While she has no inclination to face the dangers of the trial, she unexpectedly becomes very protective of Teen when he offers himself as her replacement. Could there be some maternal instinct kicking in? Possibly. Jen recounts a rumour that Agatha had sacrificed her child for the Book of the Damned (the Darkhold?), and if that were true, she doesn't seem willing to repeat the experience. The glimpse she has into her past suggests how horrified she is about what she did, but it's too early to say. Terrible friend though she is, she is a terrific coach, giving Jen a heartfelt pep-talk that snaps her out of a panic attack, allowing her to complete her crucial task.
Teen, the Gen-Z representative comes in clutch navigating the trial which is set in a modern yuppie house. Making use of the kitchen sink as a makeshift cauldron, Jen the Potions witch needs to bring her brew to a boil fast. Teen immediately comes up with a 21st Century solution. In fact, early in the episode, Teen figures out that the trials are meant to be faced without witchy magic but with practical magic, emphasis on the "craft" in "witchcraft". This realization opens up for us a glimpse into the witchy codenames for what are otherwise ordinary household ingredients like "eye of newt" referring to mustard seed, and "gut of a eusocial insect", meaning honey. We also learn that none of Agatha's coven can hear Teen's backstory either. It's been censored by a sigil that keeps his secrets secret from the witching community.
It is Jen's expertise that is under trial in this episode. It is up to her to remember the ingredients of the potion needed to save the lives of their coven. A vision of her past shows how terrified she is of a mysterious Victorian-looking man who calls her "an inconvenient woman", appears to have abused her and possibly stolen her power. When Jen freaks out, being unable to remember the last ingredient of the potion, Agatha reminds her that knowledge IS power. Jen the fraud, the scarecrow, finds her brains and completes the potion, ending the first trial. Jen is the first to name-drop, Mephisto, who is widely speculated to make his MCU debut in this series, but it could be just as well be a fan service red herring.
We get only a fragment of Lilia's past in her vision. Giving off a Renaissance horror vibe, her vision hints that her trauma has to do with survivor's guilt. "They're all dead", Lilia says in Italian when she returns to reality. If Lilia is the Lion, she may have stayed quiet and hidden while she watched some horrific event happen to the people around her. As such, her trial may have to do with confronting her act of cowardice. We'll see in subsequent episodes.
Similarly with Alice, her vision is fragmentary. It speaks of a generational curse, and hints at Alice's abandonment issues. She tells Teen that her mother "wasn't well", and in her vision, her mother drinks out of a suspicious-looking vial immediately after declaring that she was "next". Perhaps the heart Alice the Tin-man is looking for has to do with forgiveness for her mother.
'Mrs Hart'. The whole of this episode, she has been responding as a normal, non-magical person would, having been dragged unwittingly on a magical journey. She constantly reminds us that she is "Sha-ron" which is the identity badge she carries around with her throughout the episode. She is endearingly hilarious with her lines and behaviour. Her character is built up a lot, so what happens to her at the end is unexpectedly heart-wrenching. With Agatha simply responding "Who's Sharon?" to close the episode, I suspect that the human "Sharon" identity will take on a new magical form, which would be crucial at the trial of the Green Witch. Or if Rio Vidal is actually meant for this task, it's important for Sharon to be separated from this group so that she can transform into the Good Witch whose role is yet to be filled.
No sign of Rio or the Salem's Seven, but I believe their absence gives us a chance to understand the underlying motivations of our main characters before pursuit begins again.
