Grey's Anatomy Photo Gallery: "Can't Fight Biology"

at .

Grey's Anatomy is all-new tomorrow with "Superfreak," an episode built around the arrival of Amelia Shepherd. The following week, "Can't Fight Biology" should be just as intense.

Lexie loses it when Meredith and April grow closer, a car accident brings in multiple traumas, Jackson tries using his looks to get ahead, and Cristina's self-doubt causes new issues.

Things become hostile on all fronts when a visit to the obstetrician results in some disturbing news for Meredith and Derek. Fortunately, they don't seem too bothered right here:

Perhaps this is more of the sex-crazed McDreamy we've been promised, but the visit to the OB sounds pretty alarming. Any thoughts on what it could mean for MerDer?

Nathan: What? I mean, I'm going to try not to be offended at that.
Arizona: No, no, no. It's just that Derek was, Derek was epic for her. They were the great love story. I mean, that girl's heart beat for Derek Shepherd. It just, it never occurred to me that she would ever be with anyone else. He was perfect. He was everything. That man turned her world. It, I spooked you. Don't be spooked.

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."
