I'm not compelled by Flower's inferred allegiance a bit, thoroughly made my case that wise, but Dyna looks like one of the grandest threats either right now, potentially. I also feel particularly low compelling: Melontonin, LANJI, RippedCal.
And I don't like Flower's argument on the transversal divergence between her and Melo, since this is patently a game featuring multiple sides. Expecially indie sides.
