“blanche” is from a medieval french nickname meaning "white, fair" and it is also associated with being a pure and royal name.
“blanch” (without the “e”) in english similarly means “to take the color out of; bleach” or “to become white; turn pale” (those pale schnees and their white names)
team mystic values logic and wisdom, and blanche is all about researching how and why pokemon evolve (sounds a lot like weiss to me, especially the whole “with our calm analysis of every situation, we can’t lose” even though one of the last times weiss analyzed a situation, she lit the forest on fire…)
the team mystic mascot is articuno, the legendary pokemon that has the ability to control ice. it’s an ice pokemon. enough said.
HAVE YOU SEEN BLANCHE????
i’m not saying they’re similar, but they’re totally similar.
blanche has that white hair going on, stern expression, that trench coat thing… definitely has the schnee look.
all of the fanart i’ve seen shows blanche with a ponytail, and gUESS WHO ELSE WEARS A PONYTAIL??? THATS RIGHT, IT’S WEISS.
lots of people associate team mystic with being the “snobby, know-it-all, too good for you” team out of the three, and if that doesn’t scream schnee (at first glance that is) then i don’t know what does.
anyway, this obviously isn’t legitimate or anything, i just remember thinking blanche’s silhouette reminded me of winter when i first saw it and now after the reveal of the team leaders, i thought blanche looked like a schnee cousin or a long lost sibling. these are just the first things i thought of and typed them up for my own amusement.
