Frech speaker here, lightning in french is éclair, which is pretty close to éclaire which is a baked good. Guess the family did try theme naming… they just didn’t do enough research.
I’m sure you’re gonna get 20 asks about this but I can’t resist being the obnoxious Frenchperson telling you that Éclair is not only a pastry, but also means lightning (without an e in either case, that is Wildbow’s mistake or the girl’s).
Oh, huh. Sounds like a very shocking pastry!
