Mere tells her that it's not about the surgeries and it's not about getting ahead. Izzie asks if it's just about the hot sex then. "I mean, Meredith, what the hell are you doing?" Meredith rolls her eyes and doesn't respond. "Oh my god..." says Izzie. "You're falling for him." Well, DUH. Mere says she isn't. Izzie says she is. Mere says she isn't. "Dammit," says Izzie. "You poor girl." Oh, first you hate her, now you pity her? At least she's getting laid, IZZIE. Mere's all, he's just so...and there's like...and the thing is...and I'm having a hard time! Izzie's all, you're mushy. And confused. And sad. You're definitely falling for him. She cuts Mere a piece of cake. "I hate you!" says Mere, grabbing a fork. "And your cake!" Izzie giggles and says her cake is good. "So, um, how hot is the sex?" asks Izzie. Mere's prudishness kicks in. "Izzie!" "What? Come on! I'm not getting any! Help a girl out with a few details."

We don't get to hear the details, unfortunately, because we have to check in on Alex as he's on the rowing machine and angrily tossing down the handle because he's so damn angry about Digby. "Maybe we like the pain," says Mere's voiceover. "Maybe we need it. Because maybe without it, we're just, I don't know..." Derek and George check on Jaime as Burke goes to check on Cristina. She's not in their clandestine meeting room of sex, though. "Maybe we just wouldn't feel real," continues Mere's voiceover as we get a shot of Cristina in the bathroom with a pregnancy test. And another pregnancy test. She took two and I'm thinking she didn't pass with flying colors.

Later, Mere and Dere get ready for bed and he says, "You know, we could just..." "Sleep?" Mere interjects. "We could, yeah, if...if you want to," he says. Heh. He looks wrecked. So does she. They both collapse into the bed with their clothes still on. "What's that saying?" asks Mere's voiceover. "'Why do I keep hitting myself with a hammer? Because it feels so good when I stop.'"

Next up on Grey's Anatomy: Mere keeps hitting herself with a penis hammer. Oh, and Cristina's preggers. And it's not pretty.
