After that V.V. kidnapped her in the first season, we find out that now she's with Suzaku. She became Governor-General of the Area 11, because she would continue what her sister Euphemia did. She talked with Lelouch and he told her to play as she doesn't know anything about him.
She "faced" Zero, trying to convince him to change the world with kindness, disappointing Lelouch.
Thanks to her name, we can see that she gained again her royal status.
