Regardless, it was easy enough for Nyles and Sarah to cross paths in the final version of Palm Springs, although unfortunately for the latter, she ignored the former’s advice to stay away from the freaky glowing cave and ended up getting trapped in this Groundhog Day-like scenario with him and J.K. Simmons’ Roy.
Had the movie stuck with Nyles going to Palm Springs to eventually die, it’s unclear how he would have met Cristin Milioti’s Sarah, and whether she would have already been living there or was visiting the location for another reason.
