Er, what I meant was, I was personally thinking Glynda's and/or Crimson's midair symbols/glyphs/circles (whatever you wanna call it) were similar to spellcaster's circles. Doesn't necessarily mean they're actually spellcaster's circles... But that's for a different topic altogether.

On to the topic at hand :

The quite short (and spectacular) burst of flame when Yang gets 'fired up' (literally and otherwise) could possibly be her aura 'activating', and the red eyes be her indicator of having it active... (speaking of which there's a possible inconsistency, between 01:32 and 01:33 that shows Yang's eyes as her normal lilac instead of aura-activated red... Will take screenshot if/when I can for submission...)
