Jake tells Terry he hasn't been to the dentist in 7 years. In season 1, he said he hadn't been in 8 years. Both statements are wrong because he is seen at the dentist in season 1.
Holt calls an arsonist Dirtbag, later he says that this is a compliment.
Charles has Jake wash his dogs, two of which are Richard and Dan, introduced in Pontiac Bandit (2014). However, Richard and Dan are Cheddar's offspring, and Cheddar is a corgi. Corgi mixes cannot grow as large as the dogs seen portraying Richard and Dan.
Captain Holt wears his Commendation breast bar above his World Trade Center Breast Bar. When the WTC bar is worn, it is worn above all other medals, but below the American Flag bar.
When the team are trying to get into Terry's email account they ask the system administrator to help guess the password.

Holt asks Amy to bring the case files to his office whenever she can. A minute later, he leans out of his office and says, "Now means now." He never said "now" and his original statement did not imply a sense of urgency that would warrant such a reaction.
When Jake opens his email program on his computer to check about Terry's mail regarding Enzo "Hurricane" Davis, the signature in the mail says "Det. Terry Jeffords". He actually is a Sergeant (Sgt.), and the sender in the program says "Sgt. Terry Jeffords".
Holt says that the meat is tainted which is why he had the bathroom emergency. In an earlier episode he says that he hadn't drunk milk for 19 years because it upset his stomach. The sauce that is put on the street meat more than likely had milk in it which would have caused some upset in someone who had not had any milk based product in over 20 years.
Jake says that he was the one who convinced Terry not to get a vasectomy. In Chocolate Milk (2014), Terry admitted while under anesthesia that he did not actually want the vasectomy. Jake merely had to enforce Terry's unfiltered wishes.
