and the interesting thing about that flash of light is we have no idea what it did. Jaune was healed in there somewhere, which may or may not be standard for Aura. Cardin was knocked flat, which could have happened if Jaune's aura had exploded in a way similar to Ren's. Either of those effects could be nothing to do with the semblence, but equally possibly could have been everything to do with it. I can think of dozens of ways of achieving one or both of those effects.
