Just to remind you, here's what Joss had to say about Miracle's new character in his post here on whedonesque back in October, when he first revealed all the changes that have been made to the show:
Similarly, the character of November has fallen out of the mix, because the show simply moves too fast now for me to do what I wanted with her. Season three, anyone...? Happily, Miracle Laurie is still with us in a new role, playing against (and pining for) Tahmoh's character, Paul Ballard. Their chemistry is deeply nifty.
