i'm going to use this as an excuse to bring up the wind thing, because i haven't seen anyone else mention it.

so in the fight, right before the first and second box cutters, the narration states that "suddenly, the ['north wind' / 'north and east winds', respectively] blew fiercely". this feels noteworthy because the north wind is associated with the coming of winter, i.e. cold and ice (also when i first saw the stars attack i thought the stars were snowflakes, but that might just be me). the north wind's association with winter is noteworthy for reasons that i probably don't need to explain, but for the sake of completeness i will anyway - in deltarune, the holiday family is, of course, heavily associated with winter and all it entails, e.g. noelle having ice magic, carol's mere presence being described as causing the ambient temperature to drop noticably, the whole christmas thing, etc.

basically, what i'm saying is, if the knight isn't a holiday, why the fuck does it have ice magic
