Warning! This post contains SPOILERS for Agatha All Along episode 7

Agatha All Along episode 7 is full of several exciting Easter eggs and MCU references, including major connections to earlier events in this new Marvel series. Facing the next trial on the Witches' Road, this new test sees Lilia Calderu (Patti LuPone) taking center stage, offensive witch stereotype costume and all. As a result, this new episode features some pretty cool Easter eggs as Lilia's powers of divination and struggles with her own personal timeline are finally revealed in full.

The origins of Teen's backstory as William Kaplan/Billy Maximoff were finally revealed in Agatha All Along episode 6. Now, this new episode sees Billy (Joe Locke), Agatha Harkness (Kathryn Hahn), Jennifer Hale (Sasheer Zamata), and Lilia facing the next trial held within a dark and menacing tower while dressed as iconic witches from movies and pop culture. To that end, here are the biggest Easter eggs and reveals in Agatha All Along episode 7.

13 Lilia Is Dressed As Glinda

The Wizard of Oz's Good Witch of the South

Seen falling at the very beginning of Agatha All Along episode 7, Lilia is featured in this episode dressed as Glinda, the Good Witch of the South. Hailing from The Wizard of Oz, Glinda is one of the most well-known witches in pop culture, having helped Dorothy Gale make her way back home to Kansas after her house landed in the land of Oz. Naturally, Lilia is repulsed by the costume (another demeaning stereotype of real-life witches in the MCU). Glinda's also been portrayed by several different actresses over the years, including Ariana Grande in the film adaptation of the Broadway musical Wicked.

While LuPone is obviously no stranger to Broadway, she's never performed in Wicked.

12 “Yes...No...Maybe...”

Is Wanda Maximoff Alive?

Billy asks Agatha Harkness directly if Wanda is dead at the beginning of this episode. However, all he gets is a very cryptic response. Even though Agatha says she saw a body, she was the only one who did, and it was when she was still under Wanda's spell. As such, the ambiguous nature of Agatha's answer feels extremely intentional, with Marvel Studios clearly wanting to leave the door open for The Scarlet Witch's possible return in the MCU's future.

11 Agatha Is Dressed As The Wicked Witch of the West

"She's Based On Me..."

Conversely, Agatha finds herself dressed as the Wicked Witch of the West/Elphaba, also from The Wizard of Oz and Wicked. Hilariously, Agatha tells Billy that the classic villain was based on her, though Billy seems doubtful and tells her to prove it. Regardless, Kathryn Hahn's Agatha pulls off the black and green quite well. Additionally, actress Cynthia Ervo plays Elphaba in the Wicked movie opposite Grande's Glinda.

10 Billy Maximoff Is Dressed As Maleficent

"If The Cheek Bones Fit..."

Billy Maximoff is dressed as the classic Disney villain Maleficent. Originating from Sleeping Beauty, Maleficent is the imposing witch who creates the spindle that curses Aurora and later turns herself into a dragon by the movie's end. Maleficent has also received a pair of live-action movies starring Angelina Jolie as the titular witch. Unlike Jennifer and Lilia, Billy is a big fan of his outfit, especially due to his similarly prominent cheekbones.

9 Jennifer Hale Is Dressed As Show White's Hag

"I Don't Want To Talk About It..."

Jennifer Hale finds herself dressed as Snow White's Hag upon entering this new Witches' Road trial. Transforming herself into a hag to trick Snow White with a poisoned apple, the Evil Queen was Disney's very first villain in their first full-length animated feature. That said, the MCU's potions witch is less than enthused about the get-up.

Gal Gadot will be playing the Evil Queen in Disney's live-action remake of Snow White.

8 Agatha Calls Lilia "Dory"

Short-Term Memory Loss

As Lilia struggles to orient herself within her own personal timeline, Agatha refers to the divination witch as "Dory". This is undoubtedly a reference to the animated blue tang voiced by Ellen DeGeneres in Finding Nemo and Finding Dory. As seen in both Pixar movies, Dory suffers from short-term memory loss, hence Agatha's name-calling as Lilia attempts to things out of sequence.

7 Billy Maximoff Pulls The Magician Tarot Card

Teasing The Demiurge?

Doing a Tarot reading for Billy, Lilia pulls "The Magician". Calderu herself refers to this card as fitting as it signifies that Billy is quite powerful with "great potential to turn his goals into reality". This could very well be a tease that Billy has only scratched the surface of his powers and a possible hint that he may not only become Wiccan in the MCU, but also the fated Demiurge. In the comics, Billy is destined to become "The Demurige", one of the most powerful beings in the entire Marvel Universe with immense powers over creation and reality itself.

6 Lilia Foresees A Reunion For Billy

Tommy? Or Someone Else?

During his reading, Lilia also foresees an imminent reunion for Billy. Naturally, BBilly hopes that this reunion will be with his twin brother Tommy, the entire reason for his journey down the Road. However, it's also possible that it could be someone else, such as the Scarlet Witch or even the Vision.

5 "Death Comes For Us All"

Came From Lilia's First Coven

During an earlier trial when Billy was near death in Agatha All Along episode 4, Lilia can be heard saying "Death comes for us all". Now, Agatha All Along episode 7 reveals that this phrase originated from Lilia's original coven in Sicily, before they all died from fever, as was foreseen by Lilia.

4 Rio is Confirmed As Lady Death

The Original Green Witch

At the end of Agatha All Along episode 7, Lilia discovers that Rio Vidal is none other than the embodiment of Death herself. Revealed to be the original Green Witch, the episode pays off multiple previous clues that were seeded throughout the show that Rio is indeed Death (and that Agatha knew who she really was the entire time). As such, it will be fascinating to see just how powerful Rio truly is in the final two episodes.
