Speaking of Weiss, does this episode technically confirm that her black glyphs are in fact dust-infused? The only time we've ever seen her glyphs change color is with dust or by another person's aura. And she has consistently carried gravity dust from day 1, given purple has always been in Myrtenaster

Hard to say. When she uses her white glyphs they act like a springboard that propels her forward. However her glyphs have also been shown turning black which have the opposite effect, holding things in place or pulling this backward. It is possible she is using Gravity Dust to make the glyphs turn black, but I don't know.
