I'm afraid there's nothing listed for this season. Add something here!
Dedication - S1-E15
Continuity mistake: At the start, Frank isn't wearing glasses at the table. Then in one shot he is. Then not again. (00:00:40)
Frank Reagan: I'm the PC. I know everything.
Trivia: In episode 2x22 "Mother's Day" the scene at the start was filmed at Brooklyn's American Veterans Memorial Pier, at Bay Ridge Ave aka 69th St, in Bay Ridge (off Belt Pkwy). The location and design of this pier is distinctive and also sentimental (particularly to older Brooklynites).
Question: What is the significance of the lapel pin worn by detectives on Blue Bloods?
Answer: It is an NYPD Detective Bureau lapel pin. If you zoom in on a pic of "Danny Reagan," you will see that the pin has the letters DB on it.





Answer: It is the lapel pin worn by members of the NYPD Honor Legion.
The lapel pin is on Danny but not Biaz, why? Also, Baker, Sid, Frank &Garrett wear one. Significance? Are they all the same?
Is the P.C.'s pin different than a legion pin? What are the symbols and their meaning?
I think it may be Masonic?
But why would the mayor wear one?
