Jake says "The Dragon" is his first perp with a cool nickname; seemingly forgetting Doug Judy the Pontiac Bandit.
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.
Jake says that he knows Holt was already in a bad mood when he arrived at work because he was the first one there in the morning, implying that Jake was the only member of the squad already in the precinct when Holt arrived and thus the only one who could have been there to judge his mood. It is later stated that Holt arrived at 10 that morning. The 9-9's workday typically starts at 9. If Holt did not arrive until 10, the rest of the squad should have already been there for about an hour.
