Alex and Arizona have gone to collect the organs, and she's babbling on account of her not liking to fly. She tells Alex she met Izzie and ignores every "stop talking" vibe emanating off of his body to ask if he thinks she's The One. He finally snaps at her but then semi-apologizes by way of explaining that he doesn't make plans, and that it will either work out or it won't and he'll get over it like he always does. She watches him, clearly a bit put out but I think she also feels sorry for him in a way.
Izzie, George and Cristina are sitting at lunch and Izzie says she thinks Cristina's date is a good thing. "I think you and the pig murderer make a really cute couple." She then asks what they're going to talk about, and both Cristina and Denny ask her why she cares. It's because Izzie thinks first dates are fun and sexy and you only get to do it once. Man, I wish I had some of her optimistic excitement before my own first dates -- I tend to think of the time leading up to it and possibly the date itself as a unique form of torture when you worry too much what someone else thinks of every little thing about you. Izzie then suggests she ask good questions, such as what was his best surgery ever? Cristina informs Izzie she knows how to go on a date, but they're interrupted by George asking why Meredith (still in the high ponytail) is eating pot roast? Cristina says it's a "show lunch for the mommy" and guesses that the ponytail is going to blow, while Izzie just watches with a vexed look.
Mere is smiling, but it's slightly less psychotic-looking than before. Maybe the ponytail is falling a bit and not pulling so tightly at her cheeks. Mama S asks about her parents, who Mere says are dead and Derek warningly tells his mom that Mere's mom died the year before. She then asks about Mere's dad, at which point Mere jumps up to go check on their serial killer. One tip for anyone meeting someone's mother -- letting them know you'd prefer to spend your time with a mass murderer probably isn't going to get you started on the right foot. Once she's gone, Derek says defensively that family isn't Mere's favorite topic, and when his mom points out that she didn't say anything, he tells her he knows what she's thinking. It's nice to see him actually stand up for his girlfriend here, even though I don't think she's actually made any outward, "I'm not sure about this girl," indications yet. She tells him that she was actually thinking it must be hard for him to treat a murderer but after chewing his pot roast for quite a while, he stonily tells her he's fine.
