User blog comment:ChishioKunrin/Reminder: Weiss' Semblance is Glyphs, Not Ice/@comment-86.165.118.236-20141201212759

Characters constantly referring to her as 'Ice Queen' and 'Snow Angel', her name means 'White Snow' in German, shown to use ice for the Aura WoR.

Can we be so sure that Pyrrha was so sure that Weiss' semblance was her Glyphs?
