Translation and modernization from the classic comics
--Archie: aside from the "where the hell's the tic-tac-toe board on the side of his head?" through most of the episode, the (when it came up)"wtf? doin' a teacher?" not right at all, but adding some "kick" to the series... developers are gonna do what they want to
--Veronica: having her dad be indicted and losing the family fortune--good way to keep the gray area skirting between rich bitch and "frenemy" (the whole "package deal" thing really cemented that.
--Betty: can't be too sure yet... she's medicated, but doesn't want to take the meds... (definitely pointing at a possible "psychotic personality change" story arc
--Reggie: not a big part in this episode, but expect him to be a bit more of a douchebag
--Jughead: hmm...an always eating slacker with dumb hat... imho perfect, only seen at Pop's Chock'lit Shop writing, and I can't think of any better way they could've done that dumb-ass iconic hat.
--Moose: honestly thought he'd have a bigger build
--Ms. Grundy: WTF were they thinking making old-lady Grundy into a hot young vixen? A made-for-tv character for the "teacher/Archie affair" plot could be just as easy.
