So, at least a couple of weeks have passed since the last episode, and this week's episode is all about people from the past turning up like a bunch of bad pennies. First, we discover that Susan has gone into maternal overdrive with Meredith, constantly showing up at her house and buying her groceries. As you would expect, Meredith reacts by telling Susan to back off. But Susan is persistent, and ends up forcing Meredith to admit that she kind of likes having Susan around. And then Crush's parents show up after her new face is splashed around the news. She's pretty excited, but Alex is clearly not happy about letting her leave. Fortunately for him, her parents decide they're not really her parents after all, leaving her at the hospital. Unfortunately for him, Crush is kind of pissed off about this, and she takes it out on Alex.
Colin Marlowe also shows up (again), to try to convince Cristina that she's with the wrong man and generally lord his cardio-godhood over Burke. Cristina fights back by acting disgustingly girly in order to convince Marlowe that she's really committed to Burke. This actually works when Marlowe decides that Cristina is no longer the woman he once loved, and he departs the hospital and (I hope) the show.
The last person who shows up unexpectedly is Izzie's daughter. Yeah, I know! She has leukemia, and her parents ask Izzie to consider donating bone marrow. Izzie is overcome with emotion, and ends up telling the whole story to Bailey, who is as kick-ass and supportive as you would imagine. Izzie agrees to donate the bone marrow even after her daughter refuses to meet her. George, who has still been giving Izzie the cold shoulder after the awful, awful sex, gets suspicious that something is up and ends up butting into Izzie's marrow donation. This rekindles their friendship, but throws some cold water on George's relationship with Callie, who catches him lying about where he was for the day.
And in a storyline that really doesn't fit the metaphor about people from the past turning up, Derek continues to push Weber about winning the Chief's job. Weber is not especially supportive, and it turns out that he thinks that if Derek becomes Chief of Surgery, it will ruin his relationship with Meredith. This leads Derek to think that he has to choose between Meredith and his career. So we'll all see how that turns out.
Previously, on Grey's Anatomy, George and Izzie had sex. Some other stuff happened too, but the image of the very, very wrong sex has pushed everything else out of my brain.
We start with a little surgo-montage. Meredith's voice-over tells us that a patient's history is just as important as their symptoms, while we watch Burke and Cristina operate on some dude. Unfortunately, they spend more time making goo-goo eyes at each other than they do actually looking at the patient, so I don't think he has the best chance of making it out of this one alive. Mere's V.O. continues nattering on, telling us that ignoring a patient's history, or having the wrong facts about a patient's history, can mean the difference between life and death. And I was right about the patient -- one of the two surgeons does something that causes lots of beeping and a gusher of blood shooting out of his chest. It kind of makes me think of Jed Clampett. Red gold! Texas t-cells! There's hemoglobin in them thar hills! And speaking of death (which the V.O. was just doing), Cristina looks up at the gallery and sees creepy old man Colin Marlowe staring down at her. He seems unnaturally pleased by the sight of the patient bleeding out.
At Casa Grey, Susan (Meredith's step-mother) is...putting groceries away? While Derek sits on his ass and drinks coffee. He tells her, "Meredith, she'll accept a certain amount of help and then she starts to feel suffocated." Hey, Derek, you know who might also appreciate a certain amount of help? The woman currently putting the groceries away. Get off your perky ass, lazy. Susan worries that she's suffocated Meredith. Derek, who is going to be eating at least some of the free food, tells Susan that the groceries are just fine. In fact, he's more worried that he's going to suffocate Meredith. By helping her, I mean. Not by covering her tiny head with a pillow in the middle of the night. Susan thinks that it makes sense for Derek to want to help Meredith after everything that's happened. She also lets us know that she's given Meredith "some time" after her mother's death, so I'm assuming at least a couple of weeks have gone by since the last episodes. Meredith enters the kitchen and wonders if the huge mountain of food all came from Susan. Susan: "I just picked up some things to restock your fridge." And your cabinets, bread box, and spice rack. Meredith: "You bought groceries every week." Derek: "Yeah, you have to do it every week if you want more." And this is where Derek and Susan start to get a creepy, co-parental vibe to their interaction with Meredith, as they give each other this glance that just screams, "Kids today." Alex walks in and is pleased by the grocery haul. Derek announces that he's leaving because he wants to try to speak to Richard about the Chief of Surgery thing before things get too busy at the hospital. He asks Meredith to wish him luck. Susan: "You don't need it. Just make him listen to you. You deserve to be Chief." And once again she sounds more like Derek's wife and less like Meredith's stepmother.
