So you'll have to wait longer still.

Heaven help us, the Authors could be real jerks about it and have Moiraine not express a single word until the end of the book. Then it could be something lame like "I know what we have to do!" <Prophecies Quote that I usually don't like much, no offense>

If the Authors do it "Lost"-style, it'll be far worse: Moiraine will almost say something, or possibly speak, but it won't mean anything. Then in the book's last sentences, she'll say "Hello, Rand" or "you have to kill your Ogier" or "you found a portal stone?" <horn blare> <echoey sound-effect>
