Jameson “Jamie” Reagan is the youngest of Frank and Mary Reagan. Known for having a good heart and being the ‘Golden Boy’ of the family, it is hinted that he got in the least trouble as a kid, not having been to jail until starting a fight at a wedding. Jamie has good instincts as a cop, despite having gone to school to be a lawyer. Over time he has wavered from his strict lawyer’s viewpoint and now sees things as a cop as well.


Early Life

As the youngest of the Reagan clan, Jamie was babied in many aspects especially by his mother who did not want him to go into law enforcement like the rest of the Reagan men. One of his bad habits when he was younger was swallowing things such as: Danny’s liberty head dimes, Erin’s confirmation locket, the key to the liquor cabinet, and a pair of Mary’s pearl earrings[1]. An excellent student, he went on to Harvard where he studied law and got a position at a local firm before Joe’s death inspired him to follow his heart and enter the Police Academy.


After giving up his promising law career, Jamie entered the Police Academy and graduated top of his class. He was assigned to the 12th Precinct and was assigned to his Training Officer (TO), Sergeant Anthony Renzulli. During their partnership, Renzulli more than once expressed the opinion that he could be a great cop as long as he didn’t adopt Danny’s bad habits. On several occasions, Sgt. Renzulli challenged Jamie to think more like a cop, notably the hot-dog costume wearing drug dealer. Partnered for two years, they became close and Jamie even went so far as to ask Frank for money to help Renzulli out. Jamie and Danny often see each other at crime scenes and the first body Jamie saw was shown to him by Danny, a fact he later lamented to Erin.

Shortly after graduating the Academy, Jamie was approached by the FBI, looking for his help investigating a fraternal organization of the NYPD known as the Blue Templar. They caught his interest by revealing that Joe Reagan had been working with them and even infiltrated the group shortly before his death. While initially he is considering working with them, he eventually decides not to but still investigates on his own. As the Blue Templar starts to notice his interest, so does Sgt. Renzulli. Slowly, the Templar, lead by Sonny Malevsky start taking action against Jamie. It starts from pointed conversations, moving on to the theft of his service weapon, and finally cutting the brakes on his car. Once they made the attempt on his life, Jamie finally told the family about the investigation, revealing that he believed they were responsible for Joe’s death.

When participating in his first undercover sting assignment, Jamie makes contact with Noble Sanfino who he later saves from a drug overdose. This puts him on OCCB’s radar as Noble is from a mob family that they haven’t been able to infiltrate. Eventually Jamie decides to accept going undercover as Jimmy Riordan to get inside the crime family. As the undercover is part-time, he is still able to work on the streets most of the time, although when Sgt. Renzulli begins to suspect he is hiding something it strains their working relationship. During the course of his undercover, Jamie has a few close calls with the media, first when he and Renzulli are thrown down a flight of stairs after a fake call sends them to Potter’s church, and second, when he rescues a baby from a burning building. After rescuing the baby, Frank is forced to get creative when the media demands to know the officer’s name. While he couldn’t officially take credit for the rescue, Frank does secretly give him a Meritorious Police Duty Commendation. Frank’s decision to ask Renzulli to take the credit means he also must reveal Jamie’s undercover work which is a factor in the breaking of their partnership. Renzulli moves on to take a desk job and assigns Jamie to a new partner.

At their first meeting, Jamie and Vincent Cruz don’t know that they are partners and Vinny’s attitude rubs Jamie the wrong way. Over time they manage to work out being partners but not before having a disagreement over a young suspect. While Jamie didn’t agree with Vinny’s interpretation of the boy throwing gang signs, he stuck with his partner and later laid out a few ground rules to make sure they didn’t butt heads like that again. Jamie also learns to put up with Vinny’s playboy ways. After a man commits suicide by cop through Jamie, he enlists Danny’s help to find out why and later helps him solve an old hit and run. While everyone in the 12th is hunting Pedro Mendoza, they have several close calls due to Vinny’s resemblance of the suspect. Shortly after, when violence in the Bitterman Projects escalates, Vinny is shot and killed when they fall prey to an ambush.

Upon meeting his newest partner, Jamie is shocked to realize that he has been assigned to a rookie, Edit Janko, who goes by Eddie. While their partnership starts off smoother, there are a few rocky moments, especially when Jamie’s support of her doesn’t match up with what she thinks he should do but they work through it each time. Overall, they do support each other the best they can without crossing the line into romance and without lying. They spend a lot of time with each other outside of work, finding they enjoy each other’s company.

Jamie has stayed a beat cop, partially because no one is willing to submit his name for promotion to Detective but mostly because he really enjoys the work at the street level. On occasion he has taken on cases and worked them like a Detective would because he believes in truth and justice. He even briefly considered taking the Sergeant’s exam but later said he wasn’t going to because he had decided he was done with tests once he graduated Harvard.


Sydney Davenport was Jamie’s fiancée, until she couldn’t handle the realities of the job anymore. Jamie later told Eddie that she preferred saying my fiancé the lawyer to my fiancé the beat cop. After she gave him back Mary’s engagement ring, she took a job in London for at least six months. Over the years since, Jamie hasn’t had any serious relationships although he has dated. Currently he is romantically attracted to his partner, Eddie, although they try not to act on or let their feelings affect their job so that they can remain working together. Despite this, there have been several times their relationship has been called into question, not to mention most of the cops in their precinct already think they are sleeping together. Although he may call her bossy and make fun of her eating habits, it’s his way of expressing how much he likes her.
