There's no new episode tonight, but Michael Ausiello of TV Guide reports an interesting Grey's Anatomy spoiler pertaining to Episode 11 of Season Four.

Earlier this week, we posted an article about the use of voiceover narration on Grey's Anatomy and other shows. As we know, Meredith Grey does the honors, with a few notable exceptions. One of which is coming up in Episode 11.

The new narrator for this episode is not Callie, as some speculated earlier in the week. It is Dr. Miranda Bailey (Chandra Wilson), and there's a reason behind her filling in for Meredith â€" and as you might expect, it isn't a pretty reason.

Does something serious happen to Dr. Bailey? Ausiello writes:

"Physically? No. Emotionally? Yes. Let's just say that random scene last week of Bailey at home with her husband and kid will make more sense when Episode 11 airs."

The conclusion of last week's Thanksgiving Day episode, "Crash Into Me, Part II," airs next week, December 6. That episode will be Episode 10 of Season 4. The week after that, December 13, "Lay Your Hands On Me" (Episode 11) will air.
