When the patient is taken out of the hot tub, he has no shorts on, but when he's put in bed, he has dry shorts on.
When Wilson and House discuss the Mirror Syndrome while walking to the class room, they enter a room with two doors. However, when they are seen entering the room from the inside, it has only one door.
Right after the patient crashes all the students get up. Cole leaves his folder open but in the next shot it is closed.
"Mirror Syndrome", not actually named such, has only been observed twice, in brain-damaged patients, and is not recognized as an actual disorder; additionally, the mind-reading presentation of symptoms showcased here is a sensationalized fabrication of the observed condition on which this episode case is based. This breaks with the general medical accuracy of the show. Scoffing at Dr. Foreman is also a character inconsistency for House who displays an ignorance of the real Mirror Syndrome.
House suggests that his patient has Mirror Syndrome. Foreman asks if he means Giovannini's Mirror Syndrome, and House sarcastically asks if he knows of any other mirror syndromes. However, in Season 3, the team treated a woman with just that: Fetal Mirror Syndrome.
House's threat to swap out Cuddy's birth control pills is empty, and her reaction illogical, considering she has been trying to get pregnant with increasing desperation in the previous season and continues to do so until she finally adopts a child in a later season. She asked House himself to inject her with fertility medication at one point. No reason she should even be on birth control in the first place under these circumstances.
A look at the patient board after Foreman's diagnosis of Munchausen's Syndrome: Room 404's symptom of nausea is misspelled 'nauseau'. Room 407 has a symptom of 'difficult breathing'.
