Does that mean Orange is working with him? Or that he said it under coercion or force or accidentally.
I'm going to take a wild guess that the Geass canceler's dispel effect also allows Lelouch to Geass the person again, seeing as one of the things we see when Shirley is de-Geassed is a reverse of the rotating circuit animation (which I presume is supposed to represent brain wiring.) So he'll probably just Geass the information out of Orange, who has obviously been exposed to the effect before.
