Oof, on re-watch: we see Spinel's foot in the grass as she's watching Steven's broadcast at the start of the movie (it's not obscure but I don't remember noticing or thinking anything of it on the first view) and three minutes later he's singing about his happily ever after, while she's had her HEA tossed in a black hole and that black hole into a bigger one. And now knowing what the Rejuvenator does her standing there and smiling as Steven resets her, erasing everything after learning she just wasn't anything to Pink as Pink went off to play with her new toy colony (which Spinel is also erasing). Oof. Burn everything down including herself.
