On the surface, this Lewis Carroll-reading character seems to mainly exist to spit out exposition and further deepen the conflict. But, as is briefly mentioned, Sati is actually a computer program, not a human.

Sati first appeared in 2003's "The Matrix Revolutions," and was portrayed by a young actor named Tanveer K. Atwal. Neo met her in a subway-looking realm "between your world and our world," where she was accompanied by her parents, also computer programs. "Every program that is created must have a purpose," her father told Neo at the time. "If it does not, it is deleted."

After a group of Agent Smiths assimilated Sati, Seraph, and ultimately the Oracle, the film ended with Sati creating a sunrise for Neo and the Oracle telling Sati that they would someday see Neo again. That day has clearly come in "Resurrections" as Neo actually meets Sati a couple of times without realizing her significance. While Neo is trapped in the Matrix, Sati is one of his co-workers at the game company, where it seems she's keeping an eye on the former savior of Zion. Near the end of the film, her character becomes a bigger part of the story as she lays out the plan to rescue Trinity as well. Besides her loyalty to Neo, it's implied that she might have a personal stake in the mission, since the audience is told that the evil Analyst purged her parents, and the Oracle is gone as well. Whether or not Sati appears in any possible sequels, it's safe to say that the program has found her purpose.

In "Resurrections," Sati mainly appears near the end of the film, laying out the mission. The audience is told that the evil Analyst (Neil Patrick Harris) purged her parents, and the Oracle is gone as well.

According to Jonas, she got most of her stage direction from Lana Wachowski, but did make it a point to expand on the character's heritage.

"I actually wanted to pay an homage to Sati's Indian culture. That was something that I thought would be really important," she said in an interview on the eve of the film's release. "I think globalization of characters and normalization of cultures is very important, especially in global movies like 'The Matrix.' And that's something that has been very important to Lana, anyway. If you see the diversity in the 'Matrix' movies from the beginning, it's been very, very global. So that was important to me."
