"But the good news is, biology dictates you don't have to do it alone." It's still a shock that Meredith and Derek are still currently the most stable couple on the show, but I will definitely take it after all the on-off years. She realizes that he's lost in thought and when she gets his attention, he admits seriously that he doesn't want her to be alone if anything happens to him. Mere admits with a cautious smile that they would make pretty babies, and he beams as he realizes she has been thinking about the subject of little ones. That said, she immediately tells him they aren't making the babies now, and they agree to just practice. "You can waste your whole life wondering, but the only way to find out what kind of parent you'd be is to finally stop talking about it...

"...And just do it." Oh dear. I hope she's not telling Teddy and Mark to just make some babies just yet, as that's who we join, with Mark drizzling chocolate sauce down Teddy's spine and then slowly licking it off. He tells her he wants her to enjoy herself, and while she clearly is, she's also struggling with something and admits she needs to be honest with him about something. Mark, who is generally more perceptive than he is ever given credit for, just tells her that she doesn't have to say anything now if she's honestly enjoying herself. When she tells him she is, he says that for now that's as honest as she has to be. I wonder what she wants to admit, and if it's that she's still thinking about a certain ginger former Army Major, and if he's not too worried about it because he's possibly thinking about a particular now-blonde resident. They start to get down to business when the doorbell rings, and then keeps ringing over and over, so Mark goes up to shoo whoever it is away. Unfortunately, it's Sloan Sloan, mid-contraction and yelling that the baby is coming right now. I guess this is the annoying tradeoff we get for not having to deal with Izzie any longer.
