House

While Rachel calls Taub the first time, the carrier indicator says "No Service," which means that the phone isn't able to accept calls at the moment.

When Wilson holds up the Vicodin bottle he says there was a month's prescription in it three days ago and it's now half empty. However we know from previous episodes that a day's recommended dose is six tablets, this means the bottle should have held 180 tablets and it is much too small for that.

Trivia: Chase's GPS shows that Princeton-Plainsboro is on Prospect St.

We see that Martha Masters has a roommate. However, earlier this season in "Small Sacrifices," she said that she lived alone.

House says to Taub that hitting him with the helicopter is a negative reinforcement. It is in fact a positive punishment.

Assuming that the time on House is equal to real time, it would be March in New Jersey. Why is the outdoor pool open with people sunbathing in bikinis? The temperature in New Jersey at this time of year would be about 40 degrees Fahrenheit.

When the patient is ready for the MRI, his hands are crossed on his chest. The camera angle changes several times from outside to inside the machine. Each time the angle changes, his hands cross and uncross.

House's drivers license shows his address to be on Baker Street, the same as Sherlock Holmes. This is the first time that the street address has been confirmed, although 221B was revealed in prior episodes.

House's drivers license reveals his birthday to be May 15, 1959. However, the medical bracelet House was wearing as a patient in "No Reason" showed his birthday to be June 11, 1959; the same as Hugh Laurie's actual birthday.

Rachel says that her brother hit Taub five years ago because her brother had just found out that Taub had an affair with his boss' daughter. However, Rachel did not know about this affair until the season 5 episode "Adverse Events," which took place in 2008.

When House is trying to save the dad, his protective suit isn't entirely sealed. The bottom of the pants at his feet aren't closed.

Trivia: The game House is playing while lying in bed is the game created by the patient in the season 6 episode "Epic Fail."

Wilson is in the opening differential, but there's no reason for him to be there. He rarely sits on differentials, and only when cancer might be involved, or under other extraordinary circumstances. Here he doesn't even stay long enough to discuss the case.

At the end of the previous episode (and in the flashback this episode), House has a bloodstain on his left cheek which is very dark in the center. Yet here, the stain is not dark any more.
