Spoiler:

It came up in the generic discussion about his members loyalty with him by not removing his mask, but it would seem that even after all Zero has done his members still dislike the fact that he won't show his face. I managed to make out that his members learn that Lelouche isn't Japanese, and neither is the Kyoto leader. It would seem Lelouche was ready to entrust Karen with seeing his face, despite the risks people mentioned.

So this Laksharta woman developed the new knightmares i.e guren/lancelot and now Lelouche has revealed his face to that old man who apparently runs the Kyoto side of the rebellion.

As far as the romance side it would seem that Lelouche killed Shirley's father probably in that landslide. She then steals a kiss as others mentioned.
