Revealing: In the opening scene during the game, one of the shots of the boy is reversed. You can see that the text "Tartans" on his jersey is mirror imaged.

Continuity: The text with the symptoms written on the board changes several times, watch the letter F on the left. Sometimes it has a line across it, sometimes not.

Factual error: House is playing 'Metroid: Zero Mission' on his Gameboy at various times. The Metroid series does not feature space monkeys, nor are there distinct levels. The sounds coming from the game in the show do not match it in real life, and Samus morphing into a ball is most definitely not a failure state.

Continuity: When Robert is telling Allison about the sexual life of the patient, her reflection shows her turning around. When the shot changes, she is back in place repeating the movement.

Revealing: All the babies in the incubation room are, very evidently, dolls. When one is driven inside, his cries are heard but he doesn't mouth them.

Revealing: The baby that opens the episode is a real one in the close shots and a doll in the others. First of all he doesn't move, and second, his skin colour is totally different.

Continuity: The first baby dies on December 2nd. House's clinic patient is four months pregnant, and is given an expected due date in late March. Her due date would actually be in early May, if she's in her fourth month in early December.

Revealing: Exactly ten minutes to the end, the couple with the baby Maxine are waiting to hear how she is doing. The mom and the husband are sitting on a bench outside the room in which their daughter is being treated. The mom lies down on her husband. She is supposed to have given birth only recently, so she still has a big tummy. As she lies against her husband, however, it is clear that she is wearing a prosthetic stomach: her blue T-shirt tucks and crinkles into and around it in a way that shows it is not an organic part of her.

Continuity: Dr. House is listening to a patient's heart with a stethoscope. However as the shot cuts to his face you can see the stethoscope is not in his ears.

Continuity: When House is taking to Luke about the Vitamin K deficiency and eating the hamburgers, the lid on the tomato sauce bottle is alternately open/closed between shots.

Visible crew/equipment: 7 minutes and 30 seconds into chapter 3, Dr. Cameron and Dr. House are walking through a hall-way and Dr. Cameron's mic wire is very evident under her shirt.

Continuity: As Cuddy is making the deal with House, how much time off from Clinic duty for a week off his vicodin, while the camera is behind Cuddy you can see there is bright sunshine on House's head. The shot switches to a camera behind House and now his head is shaded.

Continuity: During the scene where Dr. Chase and Dr. Cameron are out having a drink, Cameron picks up Dr. Foreman's cell phone. Before she does she takes a drink of her soda. This drink drops the level of drink to half full. When Foreman returns a few seconds later she suddenly has a glass that is 3/4 full. There was no time for anyone to give her a refill.

Continuity: As House describes the lady's symptoms, in the front shot Chase has a small book/pamphlet in his hand. The camera changes to a side shot in the middle of House's description and suddenly the book is on the table and no longer in Chase's hand. This happens right in the middle of House's line and Chase doesn't make any quick movements to account for this discrepancy.

Other: House has Metroid Hunters on the DS next to the gangster's ear and it shows Samus in a ball rolling around. The way she was rolling couldn't have been achieved because House was holding it, his fingers nowhere near the buttons on the game.

Continuity: At the very end of the episode, House enters the conference room and stands up in front of the whiteboard talking to his team. When he first enters, the board is full of writing, then in the next shot there are only a bit of marks here and there.

Continuity: When House writes "temporary psychosis" and circles it on the white dry erase board, both the words and circle change repeatedly in the following shots.

Continuity: House puts down his Gameboy with the cover up and reaches for his vicodin. A couple of seconds of Foreman looking at House and the shot returns to House, as he is still getting his pills, but now the Gameboy's cover is down.

Continuity: Foreman is doing a sonogram of Mary's brain. As she comes out of her absent seizure Foreman's probe jumps from the left side of Mary's head to her right.

Continuity: When the young swimmer is about to dive, you get a close-up of both her heels going over the edge. Then, it shows a further shot with only one heel over the edge. Later in the same scene, the girl is underwater and you see her hair flowing around her face. When she lifts her head out of the water, her hair is tied up.
