Mandy Moore to Reprise Grey's Anatomy Role

at .

The traumatized doctors of Seattle Grace Mercy West will be trying their hardest to get back to normal when Grey's Anatomy returns for its seventh season next month, but reminders of the murderous tragedy they collectively witnessed will be everywhere.

Specifically, Mandy Moore.

The singer and actress, who played a memorable role as a patient in May's two-part season finale, will be returning to the show in the sixth episode of the new season.

From MerDer time bombs to a shaken-up Cristina and a couple we know getting married, the new season will clearly be influenced by the last. How does Mandy fit in?

Mandy's character, Mary, was the unfortunate patient coping with a colostomy bag when called upon to assist Bailey in her ultimately unsuccessful, desperate struggle to save the life of gunned-down Mercy West transplant Charles Percy (Robert Baker).

No word yet if Mary's cute hubby Bill (Cougar Town star Ryan Devlin) will be returning as well, but we're interested to see what her new guest stint means for the doctors - Bailey in particular. Will it just bring back haunting memories of that fateful day?

Are you excited to see Moore return to Grey's Anatomy? Discuss below.

Grey's Anatomy Quotes

There's a reason I said I'd be happy alone. It wasn't 'cause I thought I'd be happy alone. It was because I thought if I loved someone and then it fell apart, I might not make it. It's easier to be alone, because what if you learn that you need love and you don't have it? What if you like it and lean on it? What if you shape your life around it and then it falls apart? Can you even survive that kind of pain? Losing love is like organ damage. It's like dying. The only difference is death ends. This? It could go on forever.


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."
MEREDITH: "It is done."
