I somehow thought the speedster girl from "I'm a Virgo" was from the boys and I went into season 4 believing Sage was a speedster. Kinda dumb, BUT I think it could be plausible! Like maybe she used speed to read herself into being the smartest person on earth, but now she's depressed cause shes just watching the world repeat mistakes in slow motion. There's lots of little details in the show that could prove this: She listens to a sped up audiobook(or something) when we first meet her. So far she's always one step ahead with pretty good timing. She often responds to someone just as they're finishing their sentences, like she's impatient. The amount of books that pile up in her room at Vought could also be a clue

These could all just be normal for someone with Brain Too Big, but we've seen them misdirect with super powers before. I think Sage's power could actually be Brain Too Fast. Am I crazy?
