Still Trying to Figure Out the Mystery Behind Palm Springs's Sweet Nana? We've Got Some Ideas

Early in the film, Nana interrupts a conversation between Nyles and Sarah to tell him that she's been to "more weddings in my life than you can imagine" and calls his speech the best she's ever heard. Later on, while talking to Sarah during what will be her final night in the past, Nana reveals that she lost her mother at a young age, just like Sarah, and ends their conversation saying, "I guess you'll be going now. Good luck."

The two conversations have led to the theory that Nana is an older version of Sarah who knows how the events will play out and is bearing witness to them. There are different variations of the theory on Reddit, but the basic idea is that when Nyles and Sarah break out of the time loop, one or both of them are sent to the past. Sarah lives out her life and somehow has a granddaughter that becomes the woman that gets trapped in the time loop. An alternative to that theory is that Sarah lives a separate life and makes it back to the wedding to watch it all go down.

The problem with the first theory is that it's genetically impossible for Sarah to begin the family that she would be born into. Her granddaughter would be an entirely different person, not her clone. The second theory could be more likely, but again, genetically there's no way Sarah and Nana are the same person. Sarah recognizes the older woman as her family, which means that she's grown up with her (assumedly) all her life. So there's no way an older Sarah could have slipped into the party and pretended to be her Nana — she's the real deal. And unless older Sarah married into the family — which is never even hinted at in the film — there's no reason Sarah would be referring to her so familiarly as Nana. Plus, Nana has blue eyes and Sarah's are brown. The movie doesn't give us any hint that either woman is wearing contacts, so it's safe to say that Nana is a completely separate person from her granddaughter.

There's more weight to this theory than the first. Though Sarah comes up with a plan to get her and Nyles out of the time loop for good, that doesn't mean everyone else who was stuck in it has gotten away too. Nana does say she's been to more weddings than one can imagine, so what if she meant that literally? If Nana is stuck in the time loop, it would make sense that she is more content with her situation than everyone else. After all, she's surrounded by her family and gets to celebrate a joyous occasion where everything usually goes down without a hitch. She doesn't seem to be in any hurry to break the time loop, though she does seem to understand when her granddaughter is permanently leaving. Makes you wonder how many times she's had to say goodbye.

This theory is probably pretty low on the totem pole of ideas, but we have to consider the idea that we're looking at this too deeply! Much like Sarah when she thinks there's some hidden lesson behind breaking out of the time loop — which leads to her "selfless" reveal to her sister, Tala (Camila Mendes), that she slept with her groom, Abe (Tyler Hoechlin), the night before the wedding — we could all be trying to assign a deeper meaning to the words of a sweet grandmother to her granddaughter.

Nana has obviously lived a couple of years, so of course, she's been to more weddings than Nyles or Sarah can imagine. Revealing the death of her mother is an obvious way to connect with her granddaughter, and when she bids Sarah good luck, it doesn't have to be more than that. Her farewell — "I guess you'll be going now. Good luck." — isn't an unbelievable thing to say when you come to the end of a conversation. It's actually pretty normal. So maybe Nana is the red herring to our Mystery Inc. gang and we've fallen for it, which is exactly what the cast and crew want us to do!
