The relationship between Callie and Erica took a back seat for much of this week's premiere, but the exchange at the end hinted at good things to come.

That is, unless a certain ex-Alias vixen has something to say about it.

Melissa George is in final negotiations to join the Grey's Anatomy cast as an intern with, an, um open mind. Or so Entertainment Weekly reports.

Michael Ausiello indicates that she's being groomed as a love interest for either Dr. Callie Torres (Sara Ramirez) or Dr. Erica Hahn (Brooke Smith).

Rumor has it that Shonda Rhimes was so enamored with Melissa George that she tweaked her initial plans for the role - which reportedly involved her being a patient in just one episode.

It will be interesting to see if this has long-term potential.

The probable hiring caps a busy couple of weeks for Grey's Anatomy casting department - The L Word's Janina Gavankar and newcomer Brandon Scott will both be new interns and Battlestar Galactica's inimitable Mary McDonnell is on board, too.
