Okay, so I've noticed a trend with the way that Doubutsu no Mori e+ organizes the order of its cards. Specifically the order goes Lazy, Normal, Jock, Peppy, Cranky, and Snooty, with the order being reset for the islander cards. If this is true, that would mean that Julia was always a snooty villager to begin with. It would also mean that Harry was originally a jock, Frank was always cranky to begin with, Patricia is normal, Masa and Verdun are jocks, Pironkon is lazy, Lulu is snooty, Violet was originally peppy, and Curlos was originally cranky (Which would make sense, since he has the smug personality in New Leaf, which is descended from the Cranky islanders' behaviors). Everything else, such as Raddle's personality, fits perfectly. I may need to do some further research on this, but I feel that this should at least be considered.
Possibly another meaning for Julia's initial phrase
I knew that "dahling", which is Julia's catchphrase, is the British and Australian affectation of "darling". Could "dahling" also be the southern US counterpart for that?
