I hope no one minds (since Donna is first on the list), but I thought I'd add in a comment
WHICH CONTAINS NO SPOILERS, and might be useful to those who are still reading. It was driving me a little nuts, so I had to go to the shelf and pull out my Greek to English dictionary to figure out the Greek words Theron uses. As you probably guessed by the root of the word, "gynaika" means "woman". Likewise, "andras" means "man" and "skata" clearly translates to a slightly stronger version of "crap".
Casey says that the term of endearment that her grandmother uses, "meli", isn't Greek, but in fact it is. "Meli", or μέλι , means "honey" in Greek. For all I know, it is only used to describe the bee product. I have no idea whether it is used as a term of endearment as it is in English.
I am again astonished that my knowledge of Greek letters is useful. (See, kids, you DO use what you learn in math class in real life!)
