Herc

Season 1

Herc and Ellis Carver typically work as a pair in Narcotics, and both are intimidated by Kima Greggs' ability and annoyed at her superior attitude towards them. All three join the Barksdale detail headed by their shift lieutenant, Cedric Daniels. Herc and Carver get into trouble early on in the investigation when, along with Roland Pryzbylewski, they drunkenly charge into a Barksdale-controlled housing project and harass a group of youths. While there, Prez pistol whips one of the youths, blinding him in one eye and nearly inciting a riot. Herc is slightly injured during the incident when angry residents begin throwing bottles and firing at the officers, but returns early from his sick leave to take part in raids on Barksdale's operation.

When young dealer Bodie Broadus punches Pat Mahon during a raid, Herc, Carver and Greggs give him a beating. When Bodie later escapes from a juvenile detention center, Herc and Carver pursue and rearrest him; finding that he remains defiant they give him another beating. Even so, the three play pool together when they find themselves having to wait hours to hand Bodie over. Herc's character is also humanized somewhat when, in a failed attempt to arrest Bodie at his grandmother's house, he apologizes to her for his rough language and listens politely as she discusses Bodie's troubled past.

When Herc and Carver intercept the Barksdale crew's profits for a day by tailing Wee-Bey Brice, Herc considers keeping some of the money, but Carver realizes that figures mentioned on the wiretap might leave them exposed. Some of the money still goes missing when the bag rips in their trunk. After Daniels confronts them about the missing money, Carver begins to suspect Herc has stolen it, until it is found in the spare-wheel well of the car. This also gets both of them on the wrong side of Daniels, who assumes they simply stole and then returned the money. Later, while raiding a drug stash in Pimlico, Herc and Carver do steal money for themselves.

With little study, Herc takes and passes the sergeant's exam, placing 18th on the list of ranked, passing officers. After celebrating he finds out that he will not in fact be promoted, likely because of past brutality allegations (none of which are confirmed, but all of which are true). Carver, however, who ranks 37, is promoted to Sergeant after acting as Ervin Burrell's spy within the detail.

Season 2

When the detail is disbanded, Herc moves back to Narcotics, investigating white East-Side dealers. Daniels brings Herc into Stan Valchek's detail investigating Frank Sobotka, recognizing Herc's stomach for the tedium of surveillance work. At Herc's request, Daniels also brings Carver back but refuses to recognize his promotion; Kima remains lead detective for the detail.

Herc is again partnered with Carver and the two investigate drug dealing around the docks area. Herc plays the key undercover role, dealing with the mostly white drug dealers in the Polish docks neighborhood of Baltimore.

The two use a high-priced listening device concealed within a tennis ball to gain information then, after the device is damaged, fabricate a confidential informant named "Fuzzy Dunlop" (an inside joke between them referencing the tennis ball's texture and manufacturer) and take payments meant for the informant to cover its cost. Through their surveillance, they are able to establish a link between Frank's nephew and the drug trade.

Herc feels unappreciated, as he and Carver are constantly relied upon to do tedious leg work for the detail, even having to install an air conditioner in the home of a judge. After being left out in the rain waiting for Nick Sobotka after Nick has already turned himself in, Herc convinces Carver they will never be respected in Daniels' unit, and they put in for a transfer.

Season 3

Herc and Carver now work in the Western District under Major Colvin. With Carver in charge, they are responsible for running the district's Drug Enforcement Unit and commanding a squad of dedicated narcotics police including Kenneth Dozerman, Lloyd "Truck" Garrick, Lambert and Anthony Colicchio.

The DEU squad is responsible for policing Colvin's unsanctioned free drug trade zone, nicknamed "Hamsterdam". Herc is critical of the Major's pet project and eventually leaks details of the zones to The Baltimore Sun. When the national media begins covering the story Hamsterdam is soon shut down and Major Colvin is forced to retire as a lieutenant.

Season 4

Herc begins working the security detail for Mayor Clarence Royce, when he accidentally catches Royce receiving fellatio from his assistant in his office. After relating the incident to Carver, Carver sets Herc up for a meeting with the political-savvy Valchek. Valchek advises Herc to turn the mishap to his advantage and quickly make rank. Herc meets with Royce, who quickly surmises Herc's desire for promotion and demonstrates his willingness to help Herc's career in exchange for his discretion. Royce calls Burrell and demands that Herc be promoted to the first opening for sergeant. He receives the sergeant's post in the Major Crimes Unit under the abrasive Lieutenant Charles Marimow, but soon loses his "rabbi" when Royce loses to Tommy Carcetti in the Democratic mayoral primary. He and Marimow clash over methods, and Herc shows no respect for his leadership abilities.

Herc takes a police camera to spy on Marlo Stanfield without Marimow or a court's approval. Marlo's crew realize they are being filmed and give fake information (prompting Herc to detain an innocent woman) and then steal the camera. Herc attributes the fake information to the fictitious informant "Fuzzy Dunlop". While attempting to retrieve the camera, Herc interviews Randy Wagstaff, who has knowledge about the murder of Lex, one of Bodie's drug dealers. However, Herc later mistakenly reveals Randy's cooperation to a conspirator to the murder, Little Kevin; this information gets back to Marlo and results in Randy being labeled a "snitch", eventually leading to the injury of Randy's foster mother and Randy's placement in a group home. Still attempting to retrieve the camera, Herc pulls over Chris Partlow and Snoop and finds a nail gun which ultimately proves to be an important clue for Lester Freamon's investigation into the murders of Lex and Little Kevin.

Kima, now in Homicide and no longer in need of a drugs informant, puts Bubbles in touch with Herc, who believes he will be able to appease Marimow if he links Marlo to a murder. Herc agrees to help Bubbles with his problems if in return he helps Herc find a witness to Fruit's murder. However, Herc repeatedly lets Bubbles down, and so, to get back at Herc, Bubbles provides him with bad information, leading him to arrest a church minister. Since the minister is African American and part of a politically influential coalition, Herc is accused of harassment and racial profiling. The ministers apply pressure to the newly elected Carcetti, and Burrell saves Carcetti's day by pushing IID into looking into Herc's wrongdoings with an eye toward finding a palatable excuse for discharging him. Herc is suspended with pay pending a full trial. One of the scenes in the season fadeout shows the I.I.D. board delivering the verdict; the phrase 'Conduct Unbecoming' can clearly be heard.

Season 5

Herc is now working as an investigator for defense attorney Maurice Levy, who has previously represented the Barksdale Organization. Herc is able to provide Levy with information from his contacts in the police, including Carver, but he is irritated when Levy takes on Marlo as a client. Herc meets Carver for drinks and admits feelings of remorse for some of his actions as a police officer. He attempts to redeem himself by making a note of Stanfield's confidential phone number from Levy's Rolodex and handing it to Carver (who then passes it on to Lester Freamon).

In the final episode, however, Herc tells Levy that a wiretap has probably been used in the Stanfield investigation – a wiretap which Levy realizes must be illegal. This tip allows Levy to keep Marlo out of prison. A grateful Levy tells Herc he has done well and invites him to dinner at his home, as Herc is now mishpochah (Hebrew for "family"). Herc congratulates Carver on his promotion to lieutenant. He is last seen in the end-of-season montage at the bar buying drinks for his former colleagues.

Production

Domenick Lombardozzi speaks with the accent of his native South Bronx, which producers did not believe Lombardozzi would be able to convincingly hide and so did not ask him to try, planning a future explanation as to why Herc was policing in Baltimore. Ultimately, in the fifth season premiere episode, "More with Less", Herc mentions having come from the Bronx when he makes a reference to his hometown New York Yankees being historically more successful than the Baltimore Orioles.

Reception

Salon described Herc and Carver as providing needed comic relief to the show and acting as a "bickering couple".
