Property developers

Mayor Royce cares greatly about those who fund his campaign as he seeks re-election through development and reform of a decayed city. Royce is quick to protect developers such as Andy Krawczyk who own development agencies and contribute heavily to his office. In turn, Royce overrides their permits to be approved by power of the Mayor's office regardless of opposition to developing in a specific area. The Grainery in Season 2 which IBS members were fighting to keep is an example.

Every month, Royce held a poker game where the developers' losses, most of which occurred by purposeful folds, would go into Mayor Royce's pockets to buy influence throughout Baltimore City's residents and politicians. Royce also is seen showing support for Senator Clay Davis, a corrupt politician who receives illegal money that contributes heavily to the support of the city administration offices. As Royce's campaign is dependent on developer money, he is stated to be "in bed with every developer" having their security as a paramount concern of his.

Police and State's Attorney's office

As Mayor Royce's office is viewed as being soft on crime by the public safety subcommittee, Royce is extremely critical of the Baltimore Police Department often blaming Commissioner Ervin Burrell solely for the department's problems. Other politicians such as Odell Watkins view Burrell as merely the "hack" of the ministers and often pass down the negative criticism of the department to the mayor's office. To improve his office's view on crime, Royce pressures Burrell to reduce it by any means necessary as a means of being re-elected.

The pressure causes Burrell to relieve two of his majors Marvin Taylor and Howard Colvin, two black district commanders whose districts' uncontrollable drug trade made them unable to reduce crime by conventional methods instructed to them by the department's upper command. Burrell was quick to criticize his own subordinates in order to protect Royce from the City Council. Because of this, Royce initially values Burrell's loyalty but is later angered by the department for issuing subpoenas against election fundraisers and making the public aware of the murder of a dead state's witness. Royce looks from there to fire Burrell upon re-election and promote William Rawls to the BPD Commissioner.

Royce is also criticized for keeping Steven Demper, the Maryland State's Attorney for Baltimore City on his campaign ticket as Demper is more interested in his elected position then pursuing justice. Demper, like Burrell is valued for his loyalty and keeps his post under Royce's rule. Following the election, Royce and Demper both lose however and a new front office consisting of former Councilman Thomas Carcetti and State's Attorney Rupert Bond take their places respectively.

Relationship with city council and politicians

Royce generally relies on Chief of Staff Coleman Parker and Delegate Watkins to help him remain eye to eye with city council members. Royce appreciates loyalty from city politicians keeping them on his campaign ticket even when their position is questionably granted. He is shown being hammered by Baltimore City Council members Tony Gray and Thomas Carcetti for the decay of the city due to the rise in crime and decline in quality of public education.

To appease the two of them, especially Carcetti whom he views as a threat to his chair, Royce criticizes Ervin Burrell and other public figures pressuring them to meet the council's demands if for any other reason to guarantee re-election. It is noted early in Season 3 that Royce receives no support from the first district represented by Carcetti as it is a predominantly white ethnic area in Southeastern Baltimore which has a history for voting against black politicians. When Royce is questioned about witness protection from Carcetti, Odell Watkins assists Carcetti in obtaining the matching funds, but Royce ignores the council's pleas which eventually result in becoming a problem in his campaign.

Royce also finds conflict with Watkins in the city's eleventh district for keeping incumbent councilwoman Eunetta Perkins on his ticket. Royce eventually lies to Watkins promising to drop her for Watkins' protégé Marla Daniels, but keeps Perkins on the ticket anyway. This causes a split from Delegate Watkins who is the kingmaker essential in keeping Royce in line with the council members.

Coleman Parker remains loyal to Royce up until the election where following the loss, he plans to help a new candidate from Maryland's Eastern Shore with Carcetti's Chief of Staff Norman Wilson. Royce also relies heavily on West Baltimore State Senator Clay Davis who when properly positioned is an instrumental player in gaining the necessary votes from specifically needed people. Davis' loyalty however is circumstant to bribery and those who protect him from criminal investigations.

Relationship with voters

Following Royce's introduction in Season 3, city voters are angered by the rise in crime and other negative attributes from Royce's office. Royce appeases the voters through criticizing and threatening to demote his subordinates such as Burrell to make the city look better. Royce is actually more concerned about creating a good image amongst city voters temporarily as a means of winning the election and is not as concerned about having his office create good permanent changes that occur based on the voter's actual needs.

To win against Tommy Carcetti and Tony Gray, Royce plays the race card in the election in Season 4 relying on Baltimore's black majority to vote for him. Royce's office figures that with their funding, Carcetti's race, black flag campaign colors, and Marcus Garvey posters that Royce appears as the best candidate amongst black voters. Odell Watkins however sees through Royce's scheme pointing out that his interest in the voters' safety is not as high as his interest in the property developers' security causing him to move his support to Tommy Carcetti which becomes the turning point during re-election.

Relationship with family

Royce is shown to be married in Season 4 but is caught in an adulterous affair with a female secretary by Officer Thomas "Herc" Hauk. After establishing Herc's loyalty, Royce grants him a promotion and keeps his affair secret. Royce's wife appears accompanying him to church on the Sunday before the election.
