While ABC is yet to decide the fate of this bubble show, the most recent ratings are encouraging, as is the fact that it's leading our poll of ABC shows readers most want to see saved.

What can viewers expect from the final trio of installments? Among other developments teased by the network: a gender identity disorder case; a birth; and a major decision by Addison.
