Bingo.
1. No, I don't speak Yiddish. Why?
"Nu" is a Yiddish word that's the rough equivalent of "so" as sentence filler. As in: "Nu, why did you make that clue so obscure?"
2. I'm also not a janitor. You people have some crazy ideas.
You can steal the Mop from Nu in combat.
3. I am the beginning and the end, the Alpha and the Omega. Or...well, maybe not, I guess. But that's one guy's theory.
In Zeal, you can read Balthazar's theory of everything: "All life begins with Nu and ends with Nu. This is the truth! This is my belief! ...At least for now."
Taitoro's turn.
