Danny Reagan (Donnie Wahlberg) is one of the children of Police Commissioner Frank Reagan (Tom Selleck) in the series Blue Bloods. Already it’s been ten years since audiences were introduced to the fiery-tempered, yet loyal and good-hearted character.
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.
His Middle Name Is Fitzgerald
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.
