Werewolves are a possibility, though so are talking wolves that don’t shape-shift in FTL.
I agree mia, that the werewolf being a love interest wouldn’t be the most original. Sadly, it seems like Ruby, being boy-crazy, might be silly enough to fall for someone like Dr. Whale in SB (Snow White had a one-night stand with him after all).If that's the case, and Dr. Whale really is the Big Bad Wold, then it seems like Red Riding Hood and the wolf have some sort of dangerous liaison in FTL.
