I believe or at least hope for season 3 that she and Morgause come back as a menacing duo. I like that the second half of each series gets some of those familiar and magical growing pains. I really hope Season 3 doesn't' feel the need to reset and be funny andhip in theearly episodes, I'd rather it get dark and step it up a notch. The original and personal diagloue and stories from the end of season 2 are really great.
You haven't seen all of Season 2? I watched it online when it aired last Fall in the UK.
