In the (kinda) time-travel comedy My Old Ass, 18-year-old Elliott (Maisy Stella) trips on a ton of mushrooms and ends up face-to-face with her older self, played by Aubrey Plaza. The older Elliott has some words of wisdom for her younger self: mostly vague bits of advice about slowing down and enjoying more time with her family. Younger!Elliott listens, and finds that guidance useful.

But older!Elliott gives herself one more specific warning: Don’t fall in love with Chad (Percy Hynes White), the cute boy working at Elliott’s family farm over the summer.

Younger!Elliott disregarding this advice ends up becoming the movie’s most compelling theme — and a thread that it shares with cinematic masterpiece Mamma Mia! Here We Go Again. (Yes, for real.)

[Ed. note: This post contains ending spoilers for My Old Ass — and Mamma Mia! Here We Go Again.]

At first, younger!Elliot is sure........
