Alongside numerous Wanda Maximoff Easter eggs, Elizabeth Olsen’s birthday is hidden in the first episode.

Of course, this is a nod to Herb being Agatha’s neighbor in Westview.

This first episode is a nod toMare of EasttownandThe Killing.

Kathryn Hahn, wearing a coat, is looking contemplative while driving a car

13.In the Marvel comics,Nicholas Scratchwas Agatha’s son.

Yes, the Fantastic Four’s Sue and Reed Richards’s son.

Nicholas becomes a powerful sorcerer and villain and ultimately leads New Salem.

Police officers investigate a forest road crime scene with blocked traffic in two images. An officer hands a person a cup of coffee

14.The painting that Agnes sees while interrogating Teen is adepictionof Macbeth and the Three Witches.

This particular painting looks like the onecreatedby Francesco Zuccarelli.

15.The dates seen on the library card also hold a meaning.

Feb. 16 is Elizabeth Olsen’s birthday.

The duo created the Scarlet Witch.

16.In the basement, we get to see Agatha’s bunny, Senor Scratchy, fromWandaVision.

Top: A lifeless hand in the dirt. Bottom: Elizabeth Olsen as Scarlet Witch looking into broken glass, wearing a crown and a dark red costume

Notably, Wanda used the bunny during her magic act inEpisode 2.

In the comics, Salem’s Seven is made up of Nicholas Scratch’s children.

They become enemies with the Scarlet Witch and the Fantastic Four.

Text reads: "Based on the Danish series Wandavisdysen" followed by "Agnes of Westview"

The foundation has “evil witch” and the Scarlet Witch’s symbol spray-painted on it.

19.While assembling the coven, Agatha and Teen meet Lilia Calderu.

In the Marvel comics, Lilia is a powerful witch with ties to Wanda Maximoff.

A scoreboard displays Westview 14, Eastview 14 with 2:26 left. It shows 'Home of the Blue Devils' and 'Dottie Jones' text in the center

Wanda was brought to Lilia by her aunt/adoptive mother, Marya Maximoff.

20.Three is an important number inAgatha All Alongso far.

21.Jennifer Kale is also a notable character from the Marvel comics.

The top shows a man peering through books on a shelf. The bottom shows a mailman walking on a suburban street

22.Jennifer makes a joke that Teen might be another “child sacrifice” for Agatha.

I’m guessing this might be related to her son, Nicholas Scratch.

23.And Alice Wu-Gulliver is another Marvel comic book character.

In the comics, Alice and Wanda investigate Dark Tongji, a powerful magician, together.

Considering, she made a point to mention her black heart in Episode 1, too.
