From what I can tell, I think she's either talking to herself or doing some sort of telepathy to someone other than Lelouch. I just can't imagine her talking to Lelouch in that sense.

As for episode 8, it certainly was a big boost from the somewhat-odd episode 7 (well, the whole cat-helmet thing anyways). I really like all the thinking and mind games that the show has done since they are so simple that they can be easily overlooked.
