Holt and Gina are having breakfast at a diner called 'Two Daughters' and he remarks that it "seems like your average greasy spoon". However, in 'The Wednesday Incident', this is the same diner that Peralta traces Holt to and it is discovered that he is a regular there.
Wuntch's commendation bars lack the black "WTC" commendation, given to all NYPD officers who served on or in the wake of the 9/11 attack on the World Trade Center. Holt, Terry, and most high-ranking officers seen throughout the series have it. Wuntch has served in the NYPD at least as long as Holt, so she should have received the WTC bar. Also, most of the commendation bars Chief Wuntch wears are not issued by the NYPD.
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.
The Vulture is wearing his commendation bars out of order. NYPD regulations require that the American flag bar be worn as the highest commendation on a medal rack.
