If you can’t wait for new episodes of Grey’s Anatomy, some fresh secrets about the next season have emerged that will tide you over during summer - stop reading now if you want to stay spoiler-free!

Fans of the Emmy Award-winning drama have become accustomed to Meredith Grey (Ellen Pompeo) narrating each episode, but it’s been revealed that another character will step in to voice-over duties.

TV Guide columnist Michael Ausiello reports that Miranda Bailey (Chandra Wilson), the cranky doctor with the heart of gold, will play narrator in episode 11 of the upcoming season.

So what’s the reason behind the switch? Ausiello remained coy, but wrote that “there’s a reason behind her temporary promotion - and it ain’t pretty”. He hinted that some emotional trauma will befall Bailey, possibly something involving her husband and young child.

Plenty of other juicy storylines are coming up: George (T.R. Knight) will finally tell Callie (Sara Ramirez) about his fling with Izzie (Katherine Heigl), while Meredith calls it quits with McDreamy (Patrick Dempsey)!

New episodes of Grey’s Anatomy will air on the Seven Network in 2008, but in the meantime fans can tune into reruns airing on Monday and Tuesday nights at 9.30pm.
