could Piper and Nova Terron be a couple?
Piper is 110 years old according to AGAHG so despite her playful/childish nature, she's basically older than many of the adults (like Arkayna's parents) which might explain why she flirts with Nova Terron.
Does anyone know how old Tazma Grimm is supposed to be? I think Nova Terron is centuries old, so it might be that becoming an Astromancer makes you age slower, so I don't know if she's actually a teenager like Arkayna/Zarya (and presumably Em) are, or if she might be at least 100 like Piper is.
If Tazma actually is older, it might make her and Dreadbane being a couple acceptable. It was implied they were flirting (maybe kissing) as it cut to black in that romance episode.
