Before the credits rolled, Ahsoka revisited the high-stakes World Between Worlds from the Star Wars Rebels animated series, a location non-animation fans need to know about before Episode 5 and beyond.
What Is Star Wars' World Between Worlds In Ahsoka Episode 4?
After being defeated by Baylan Skoll, Episode 4 of Ahsoka ended with Ahsoka Tano waking upside down on an illuminated, translucent path.
Once the frame turns and she begins to stand, Ahsoka appears to be in the void of space with other suspended paths connecting to various points in the distance.
Known as the World Between Worlds, Star Wars describes this dimension as "collections of pathways and doors between time and space."
The Star Wars: The Rise of Skywalker: The Visual Dictionary also refers to it as the Vergence Scatter and it was visualized in the Sacred Jedi texts on Ahch-To.
But while Anakin came as a surprise to Ahsoka, she's been to this place before.
In Season 4 of Star Wars Rebels, Ahsoka showrunner Dave Filoni introduced the World Between Worlds when Ezra Bridger used the Force to open a portal through a painting of the Mortis gods, the Father, the Daughter, and the Son.
Once Ezra finds himself in this strange, suspended space, he hears the voices of various Star Wars characters and can even see and access certain events in time through portals.
Upon looking into the portal, Ezra sees Ahsoka fighting Darth Vader from "Twilight of the Apprentice" in Rebels Season 2.
Right before Vader kills Ahsoka, Ezra reaches into the portal and pulls her into the World Between Worlds, saving her life.
As the two explore the World Between Worlds, Ezra is actually tempted to save his master, Kanan Jarrus (the father of Hera Syndulla's son, Jacen), through a different portal. However, Ahsoka is able to convince him otherwise.
At this time, Emperor Palpatine was also trying to access the World Between Worlds for its capabilities and projected blue energy into the realm to drag Ezra to him.
Ahsoka was able to stop Palpatine's attack, preventing him from ultimately entering the dimension.
How the World Between Worlds Impacts Ahsoka
Now that Ahsoka is in the World Between Worlds, again, she has the ability to observe and enter different points in time.
While this opens up the potential for Star Wars flashbacks and live-action versions of animated sequences, it may also allow Ahsoka to access the galaxy where Sabine is being taken and where Thrawn and Ezra are trapped.
In Episode 4, Baylan Skoll destroys the map to this other galaxy in order to prevent anyone from following him, Shin Hati, and Morgan Elsbeth.
But in the World Between Worlds, Ahsoka doesn't need a map. She just needs a portal.
This would be similar to what Ezra and the Rebels crew experienced in Season 4 when, with help from Loth-wolves and their bond to the World Between Worlds, they were transported from one part of Lothal to another in a moment.
Perhaps Ahsoka will be able to transport herself to this new galaxy in the same manner.
It is also possible that Dave Filoni revisits the Mortis lore he established in The Clone Wars, its connection to Ahsoka and Anakin, and what it means for Star Wars moving forward.
Ahsoka is currently streaming on Disney+, with new episodes debuting at 9 p.m. ET every Tuesday.
