Meredith and Susan walk out of the house with Susan's arm around Meredith's shoulder. They really do seem to have hit it off. As Susan walks away, Thatcher walks up behind Meredith and awkwardly expresses his condolences over Ellis's death. He notes that the swing that's on the porch was there when he lived in the house, and Meredith tells him nobody ever uses it because it's broken. He stops for a second and then pulls a long metal pin out of the swinging mechanism. He tells her, "I put this in there. You used to catch your fingers in it." He walks away, and Meredith gives the swing a little push and watches it swing back and forth.
In the house, a very drunk Izzie is telling George to suck it up and ask Callie for forgiveness. And an even drunker George is telling her that he's sick of always apologizing and always being in the wrong. They drunkenly babble for a while, and then both decide that Callie is pretty insecure. And what they're about to do isn't going to do much to shore up her self-esteem. Izzie realizes that George has a secret and she cajoles it out of him. And when he tells her that Callie thinks that Izzie has feelings for George (and vice versa), they both start laughing. A lot. And they end up sitting with their faces very close together and getting very quiet. But surely nothing will happen, right? Because there's never been the slightest sign that these two were into each other.
Alex is on his hot date, I guess -- he's visiting Crush in the hospital. He tells her that it was a very scary day for her and the baby, and that in the future she should be getting her medical advice from an attending. But she tells him that she trusts him -- not necessarily for medical knowledge, but to look out for her. And then she asks him to sit down and tell her a bedtime story.
Meredith V.O.: "What's worse? New wounds, which are horribly painful? Or old wounds, that should've healed years ago and never did?" In Meredith's room, she tells Cristina to move over and then climbs into bed with her. As they cuddle, Cristina asks, "Am I gonna screw up this engagement?" Meredith: "I don't know. Do you want to?" Cristina: "I don't know." Meredith: "My mom is dead." Cristina: "Yeah, she is." Damn if that isn't a Debora Cahn scene.
Meredith V.O.: "Maybe our old wounds teach us something. They remind us where we've been, and what we've overcome." Pan across Alex's sexy form asleep in his bed, with morning light streaming through the window. Mere V.O.: "They teach us lessons, about what to avoid in the future. That's what we like to think." Pan across Meredith and Cristina, still snuggled up together. V.O.: "But that's not the way it is, is it? Some things we just have to learn over and over again." Pan across a very hung over looking Izzie who turns over in her bed and sees a passed out naked George in the bed next to her. And then she looks under the covers to see whether she's naked herself.
