Danny, like the majority of his family, has a career in law enforcement and never backs down from a challenge, always seeking justice. He loves his family and protects them fiercely, and though audiences know plenty about him, there are a few surprises they may have overlooked.

His Partner Wasn’t Always Maria Baez

Danny and Maria have been partners for some time, but prior to Season 3, Danny had other partners. Most significantly was Jackie Curatola, played by Jennifer Esposito, who lasted the longest.

Danny had a different partner in “Pilot”, named Demarcus King; Danny was also briefly partnered up with Ava Hotchkiss, Kate Lansing, and Candice McElroy; Danny struggled to get along with Ava, and Kate helped Danny out of a jam in Season 3 before she left. Danny and Maria are great together, with some fans hoping for a romance between them, but it took Danny a bit to get the perfect partner for him.

Danny Was Nearly Jailed

As it turns out, he was investigating a case that was getting dangerously close to revealing the fact that Captain Derek Elwood, who interviewed Danny, had set him up, as he owed a significant amount of money to the bookie that was shot, and who was a part of Danny’s investigation.

He Helped Out Eddie

In a Season 9 episode, Danny told Eddie about what happened to Joe, their brother, who was killed prior to the events of Season 1. Danny advises her on how Jamie thinks, and offers to talk to Jamie on her behalf, with her permission, of course, given Jamie is hesitant to let Eddie join a fraternal organization.

It undoubtedly brings back bad memories for Jamie, who investigated The Blue Templar in Season 1, the organization responsible for Joe’s murder. Danny proves he’s a good brother-in-law in this episode by supporting and helping Eddie, and Jamie, by extension.

Knowing Danny, this seems like it wouldn’t suit him too well, but it’s still his middle name, nonetheless. It’s not mentioned every episode, so this is easily a bit of trivia about Danny that audiences missed.

Danny has a penchant for landing in hot water; maybe his parents Frank and Mary knew from the get-go that that was to be expected from their son and thus gave him a three-syllable middle name to make things more serious and intense when calling their son out by his full name.

He Didn’t Always Want To Be A Cop

Surprisingly yes, even the devoted Detective Danny Reagan had considered another career path at one time. In a story Danny recalled, he wanted to go as a firefighter one Halloween when he was little, and his grandfather, Henry (Len Cariou) immediately put a stop to that. Instead, Henry gifted his grandson with a police uniform, and the rest is history.

Danny Accidentally Traumatized His Niece

Erin isn’t too happy with her brother for exposing Nicky to a crime scene at a young age, and though it was unintentional, Danny scarred his niece that day and forced her to deal with something very adult for her young age.

Danny Overlooks His Personal Life Too Often

Donnie Wahlberg agrees that his character is somewhat negligent when it comes to any problems in his job or his personal life. Danny is focused on getting the job done, but he tends to overlook his own personal woes, especially since losing his wife Linda. Fans, like Danny, may get wrapped up in his cases and forget that he’s dealing with some serious things in his life.

In an interview, Wahlberg mentioned that he’d like to see Danny deal with some of his past trauma in the upcoming eleventh season, and that could definitely mean new storylines and opportunities to explore the character in a new way the show hasn’t before.

According to Wahlberg’s Instagram, he’s kept a picture of none other than Tracy Morgan, decked out in police uniform in an 8×10 photograph, on Danny’s desk for the past nine seasons. It’s an interesting choice instead of Donnie’s real-life wife Jenny McCarthy, or even pictures of Danny’s family, but it definitely stands out, and audiences will no doubt look for a glimpse of it the next time they catch an episode of Blue Bloods.

Donnie Wahlberg Dropped Music References In Danny’s Speech

Donnie Wahlberg is a member of New Kids on the Block, a boy band that began in the 1980s. Wahlberg mentioned that he would “sneak” a song title from New Kids on the Block in each episode back in the first season.

He listed a few examples, in which he would tell Bridget Moynahan’s character things like “hey, hang tough” and “call it what you want”, for instance. If fans listen closely to Danny’s remarks in the first season, they’re bound to pick up the references to New Kids on the Block. 

It’s definitely true. Considering in the pilot episode, Danny’s interrogation technique was seriously brutal, even shoving the suspect’s head in the toilet and beating him up somewhat. Danny is passionate about his work, and in the “Pilot”, he was searching for a missing girl and he had a deadline, so that especially decreased his patience for any antics the suspect had in mind.

He hasn’t shoved anyone’s head in a toilet lately, and he does still lose his temper on occasion, but compared to when audiences first met Danny, he’s calmed down significantly, probably due to wisdom in lessons learned.
