Here's a minor Grey's Anatomy spoiler / casting note in case you haven't heard about it yet - for the January 15 episode, "Sympathy for the Devil," Tyne Daly (Judging Amy, Cagney and Lacey) has been cast as Derek's mother! Wonder how that will go ...

Tyne Daly

In the episode, the mother of Derek (Patrick Dempsey) will meet Meredith (Ellen Pompeo) for the first time. Will this lead to some Mer-Der drama, which has been lacking? Elsewhere, Owen (Kevin McKidd) and Cristina (Sandra Oh) go on their first real date.

MEREDITH: "You don't get to call me a whore. When I met you, I thought I had found the person that I was going to spend the rest of my life with. I was done! All the boys and all the bars and all the obvious daddy issues, who cares? I was done. You left me. You chose Addison. I'm all glued back together now. I make no apologies for how I chose to repair what you broke. You don't get to call me a whore."
DEREK: "This thing with us is finished. It's over."
MEREDITH: "Finally."
DEREK: "Yeah, it's done."
