Actually, there as of now, are multiple "huh?" Characters, like Ruby didn't know what dust and semblence was, Sun had no idea about the White Fang, Yang didn't know Blake had cat ears...

Maybe later on, when there are less things to explain, Jaune would end up being the only "huh?" character left, but as of now I don't think it would be fair to single out Jaune.
