Below are this morning's Grey's Anatomy spoilers and news items, culled from Entertainment Weekly (top three) and TV Guide (final item) ...

Q: So what's this big Denny-related story on Grey's Anatomy that could but might not open the door for Katherine Heigl to leave the show?

A: I'll say this: The exit primer I alluded to does not concern any kind of health crisis. Rather, it pertains to a very dark day in Izzie's professional career that rears its ugly head again.

Q: How long is Melissa George under contract for? Not too long I hope - Grey's Anatomy is already too bloated.

A: Reports suggest she's doing at least 11 episodes, but in my recent Q&A with her, she said there's no end date. As for the bloating ... well, are in a hospital. Aren't there pills for that?

Q: President Roslin (a.k.a. Mary McDonnell) on Grey's Anatomy?! Give us the scoop?

A: She debuts November 13, and her Dr. Virginia Dixon character shares something in common with a Bones regular.

Q: When is McArmy coming back to Grey's Anatomy? And please tell me he is going to be part of the cast.

A: As you saw at the end of last Thursday's episode, Army Major Owen Hunt is back in action - and will ruffle some feathers, stat! At this time, Kevin McKidd is on what producers are calling a "strongly recurring" status, but he certainly has the potential to become a series regular.
