🚨Warning: There are MASSIVE spoilers ahead for Episode 4 of WandaVision on Disney+!🚨
1. First, Episode 4 opens with Monica Rambeau, aka Geraldine, returning after Thanos's snap, and this is actually one of the first times we've seen how someone re-materialized after vanishing.
2. Also, as Monica re-materializes, you can hear moments from Captain Marvel. Namely, Maria saying that she can't leave Monica and go to space, Carol saying that Maria has one of the best kids, and Carol calling Monica by her nickname.
3. When Monica walks into S.W.O.R.D., you can see that one of the news channels talking about "The Blip" is WHiH World News, which has been used throughout the MCU movies and TV shows.
4. While we've never met Tyler Hayward until now, in Agents of S.H.I.E.L.D., there was a Brian Hayward, who turned out to be a member of Hydra. Let's just say I can't imagine that this is a coincidence, this is Marvel after all.
5. Of course, you can spot a plaque inside S.W.O.R.D. honoring Maria Rambeau, and you can see that she still went by her nickname "Photon."
6. While walking Monica through S.W.O.R.D., Hayward mentions that they are focusing on "nanotech," which is the technology that Tony Stark uses for his new Iron Man suit in Infinity War.
7. Also, Monica acknowledges that space is "full of threats and allies," which is a nod to Monica's relationship with Talos and the Skrulls from Captain Marvel.
8. We learn that the real WestView is located in New Jersey, and in the comic books, Wanda and Vision move to Leonia, New Jersey to try to be a normal couple.
9. Probably my favorite detail/Easter egg this week is when Monica meets Jimmy Woo, and Jimmy uses the card trick that he wanted Scott to teach him in Ant-Man and the Wasp.
10. If you look closely, you can see that the slogan of the real WestView is the same as it is in Wanda's version: "Home: It's where you make it."
11. Listen, I could be WILDLY reaching here, but on the WestView sign it says, "Elevation 203." Avengers Issue #203 is about The Beast and Wonder Man searching for a young boy in the sewers. Later in this episode, S.W.O.R.D. uses the sewers to try to get into Wanda's version of WestView.
12. Speaking of comic books and numbers, Monica's S.W.O.R.D. vehicle has the numbers "8512" on it, which could be a reference to the Vision and the Scarlet Witch 12-issue limited series comic books that started in 1985. In fact, WandaVision is pulling a lot of plot points from these comics, namely their twins.
13. The drone Monica uses to try and see into WestView has the number "57" on it, and Vision makes his first ever appearance in the Marvel comics during Avengers Issue #57.
14. Also, the drone's colors match Captain Marvel's suit, so BRB, I'm going to go cry for a minute.
15. The last time we saw Darcy Lewis was in Thor: The Dark World, and since then, she's actually finished her studies and got her doctorate.
16. You can see that while studying WestView, S.W.O.R.D. notices that the forcefield surrounding the town is in the shape of a hexagon. We've seen this shape during the first three episodes of WandaVision too.
17. When explaining how she found Wanda's TV signal, Darcy says she picked up radiation that dates back to the Big Bang. If you recall, Wanda got her powers from the Mind Stone, which was created during, you guessed it, the Big Bang.
18. This is pretty obvious, but still fun to point out, we now officially know that Darcy was the one watching Wanda and Vision at the end of Episode 1.
19. On the wall where citizens of WestView are being identified, you can see that they haven't figured out Agnes's real name yet, so I'm still running with the Agatha Harkness theory.
20. Also Sharon Davis, aka the real name of Mrs. Hart, is actually the name of a supervising art director on WandaVision.
21. When Jimmy reaches out to Wanda using the radio, Dottie's reaction is cut from the broadcast Darcy is watching, but as viewers, we saw her reaction during Episode 2.
22. The names we see at the end of this episode are actually names of people who work on WandaVision in real life — yes, we are getting super meta.
23. We see Wanda's reality begin to crack yet again when Vision looks like how he did after Thanos ripped the Mind Stone from his head in Infinity War. This is also what Vision looked like the last time Wanda saw him.
24. And, yet again, Vision makes a comment about leaving WestView, but Wanda knows they can't. This is another nod to Wanda creating this reality in order to cope with Vision's death.
25. And finally, the song that plays at the end of Episode 4 is "Voodoo Child (Slight Return)" by Jimi Hendrix, which just further adds to the '60s and '70s vibe.
