Grey's Anatomy Photo Preview: "Walking on a Dream"
Grey's Anatomy is all new tonight with its 11th episode of Season 9, "The End is the Beginning of the End." For some quality previews of what's to come this evening, see our Grey's Anatomy sneak peeks.
Looking ahead to next week, Constance Zimmer makes her first appearance as Dr. Cahill, as evidenced by the photos released by ABC, and the doctors are "on edge" because of her character's arrival.
Meanwhile, Arizona struggles with the emotional and physical pain of a phantom limb, and while battling pregnancy hormones, an overly-emotional Meredith is confronted with her worst fear.
Scroll through the photos from "Walking on a Dream" and comment below:

can't wait to see Jcap's acting for this. And I love how Callie delivers speeches, she's seriously the best. She's dreamy.

Mer is holding a cooler for an organ. Her worst fear is flying and it appears she will be to get the organ.

Well, at least they didn't fire Owen, apparently... I'm relieved.
The new doc looks like what Cristina and Bailey's child would be like. I think she will bring some discipline to the hospital. Good luck trying to parent the doctors at SGMW, though! They'll never stop screwing around in the on-call room...
Can't wait to see her character!
