Despite having a patient most likely on death's door, House gleefully reports to Wilson that, thanks to his scheming, he scored a present from Kumar, who is now hated by the rest of the team. Wilson gleefully reports that he's walking House down the hallway to nowhere just because he knows it hurts House to walk. House totally deserves that, but since when did Wilson care about House screwing with his team's heads? Maybe he's still mad about being without his precious iPhone for an entire morning. God forbid he couldn't play Bejeweled while checking his Facebook account!

Taub tells Maggie that if the CA2 test is positive, they'll be able to treat Maggie with a bone marrow transplant. Good thing she's got that daughter sitting right next to her, her bones filled with healthy, matching marrow! Oh, but wait -- Maggie doesn't want Jane to give marrow because it'll be too painful. Jane says that she's totally willing to go through pain for Maggie. Hey, the poor girl already got her arm broken by Maggie's mystery illness; what difference will a few needles in the hip make? But Maggie puts her foot down. Since it's made of stone bones now, it goes crashing through the floor. How embarrassing! Not to mention suspicious. The last time someone didn't want a kid to give bone marrow, it was so he could stay sick and not have to take care of his brother and sister. But I'm sure there's no ulterior motive to Maggie's refusal, since they've already done that and if this show copied itself that would be lame, right?

Taub tells House that he found a donor with a 5 out of 6 HLA match. House finds it suspicious that Maggie refused to let her daughter give marrow, but before he can think too much about it, Taub shoves a present into his hands. He's not quick enough, though, as Agnes rushes into the room, her Present Detector on high alert. Also, she's there to inform them that the CA2 test came back negative. Maggie won't need new bone marrow, but she will need a new coffin. Agnes takes a second to look sufficiently saddened by the news of their patient's death before spotting Taub's present in House's hands. Taub looks worried that he's about to get stepped on by Agnes, but instead, she pulls a present out of her folder and gives it to House. Then she asks who gets to give Maggie the great news. House wants to do it, because he loves giving gifts as much as he loves getting them. In fact, he even gives the Cottages a present: they get to spend Christmas Eve in the lab, finding out what's about to kill their patient. Taub and Agnes look pissed, but that's probably because they know Kumar is going to stick his CD of Cool Yule Christmas songs in the stereo and put it on loop.
