Hulu's Palm Springs Ending Is Pretty Trippy — Let's Break Down What Happened

As if the ending wasn't confusing enough, there is a midcredits scene with Roy (J. K. Simmons) that has us questioning everything. After receiving a voicemail from Sarah, Roy makes his way back to the wedding and asks Nyles if he thinks her theory about the cave would actually work. However, Nyles has no idea who he is. Does this mean Nyles made his way back to reality and is now an interchangeable part of Roy's time loop or does Nyles now exist in some alternate dimension? We're not quite sure, but we wouldn't be opposed to a sequel to see how it all plays out.
