Fucking hell, I never noticed this before.
I used to think Mermaid!Jackie is nothing more than shitposting and looking too much into things. But all these bits of evidence just keep piling up and up, impossible to ignore it anymore. I swear there is something up with Jackie, there is just no way there isn't. YOU CAN'T KEEP GETTING AWAY WITH THIS, NEFCY
