Bailey finds Meredith at Charlotte and her sister's incubator, and says she heard Mere worked a miracle last night. Mere is beaming. "She came around so fast, I thought the equipment was malfunctioning!" Bailey tells Mere to go home, because she's earned it. On her way out, she turns back. "Oh, and Grey. Way to go." Mere looks in at Charlotte, and tells her, "Did you hear that? Way to go."
Izzie is sitting in the locker room, defeated. Mere, George, and Cristina walk in, and she asks if they heard. George says they did. Izzie: "My baby died. She just...died." They all look very sad, until Mere says she has an idea. She holds out her hand for Izzie to take, and some rock and roll starts up.
Cut to Alex, staring at the patient he killed. McDreamy walks in and shares, "The first person I killed, I was a second-year resident. James Hanson." He tells Alex to go home; there's nothing he can do here. Alex says nobody should die alone, and stays put.
Mere starts up her VO: "Four hundred years ago, another well-known English guy had an opinion about being alone. John Donne. He thought we were never alone. Of course, it was fancier when he said it." We fade to Rosanna's room, where Cristina is telling her not to talk, because her windpipe was perforated. She says they've repaired it, and she should be fine. Rosanna reaches out her hand, but Cristina moves back. Heartless! But not for long: she tells Rosanna they'll keep her in the hospital at least ten days, then turns and sees the security guard keeping watch. She turns back to Rosanna, leans in, and says softly, "Maybe just to be on the safe side, we'll make it two weeks." Rosanna smiles weakly, and understands the gift she's just been given.
MereVO: "'No man is an island entire unto himself.'" She and Izzie walk along a gated corridor, looking in. Mere says, "That's him." Izzie leans in and agrees, "Oh! Yeah, that's him." Who's him? I want to see him!
Cut to Addison and McDreamy, sitting in one of the OR observation rooms. Addison tells him she's lonely, and moves a little closer. Mere: "Boil down all that island talk, and he just meant that all anyone needs is someone to step in."
Cristina walks into Burke's and sits down at the table, exhausted. Burke's got dinner all on the table and is sitting there reading. When she reaches over and grabs a chip, he gives her a look of wonder and amazement. Mere: "And let us know we're not alone."
It's him! The girls have adopted a dog, an adorable terrier-looking thing who's barking and jumping and delighted to have a new home. Mere and Izzie giggle and cavort and throw dog toys, then break into hysterics when the dog starts chasing George. Mere: "And who's to say that someone can't have four legs? Someone to run around with, someone to play with..." We fade to Charlotte and Co.'s incubator, and Mere finishes up, "...Or just...hang out." Or just...fade out.
