Templeton is a young reporter who allows his extreme ambition to lead him to falsify stories. He has previously worked at the Wichita Eagle and the Kansas City Star. Templeton sees his current job as a general assignments reporter at The Baltimore Sun as a stepping stone to the Washington Post or New York Times. His prose is reflective of his personality and is often overwrought and exaggerated. Templeton's style is welcomed by Managing Editor Thomas Klebanow and Executive Editor James Whiting.
Templeton is involved with breaking a story about a drug dealer making campaign contributions and receiving profitable property deals in return. He finds his role of preparing background information dissatisfying, and he is dismissive of the paper as a whole to his colleague Alma Gutierrez. Nevertheless, Templeton is eager to write a follow-up story and requests the assignment from City Desk Editor Gus Haynes. Haynes denies the request as he has already given the story to city council reporter Jeff Price but encourages Templeton to continue seeking stories.
Templeton is part of a team led by Executive Editor James Whiting planning a series of articles about the problems with education. Templeton wins favor with Whiting when he backs his philosophy that the piece requires little context and should remain tightly focused on the schools themselves. Haynes unsuccessfully argues the alternative position - that more context increases the relevance and effectiveness of any story.
Templeton is assigned the color story about the Baltimore Orioles opening day game. He plans to write a story about a dedicated fan but his canvassing does not render anyone that fits his profile. When he returns to the paper he tells Haynes that his subject is a thirteen year old disabled boy who wanted to attend the game but could not afford a ticket. Haynes is concerned by Templeton's claim that the boy would only give his nickname "E-Jay." Haynes asks Templeton for more detail and Templeton claims E-Jay didn't want to give his name because he was truant from school in order to attend. He also says that E-Jay is an orphan who lives with his aunt and was injured by a stray bullet causing his disability. Haynes tries to verify the story by dispatching photographers to find the boy and checking the archives for a story about his original injury. When he is unsuccessful in corroborating Templeton's work Haynes confronts Templeton a second time and Templeton tells Haynes that he resents the implication that his work is fabricated. Haynes is forced to run the piece when Whiting gives Templeton his full support.
Templeton also submits a story about a mother of four who has died of a toxic reaction to blue crabs. He claims the woman's sister is collecting for a fund to pay for the children's education.
When buyouts are announced at the paper Templeton comments to his colleagues that he hopes they will get rid of some of the "dead wood" in the newsroom. Haynes is perturbed by the perceived insult to his friend veteran police reporter Roger Twigg who has accepted a buyout. When Haynes gets news of a story about commissioner Ervin Burrell being forced to retire and replaced by colonel Cedric Daniels he offers the story to Templeton because of Twigg's impending departure. Templeton is not aware of Daniels and Twigg manages to recite a quick history of his career and expresses an interest so Haynes gives him the assignment. Haynes asks Templeton to canvass for react quotes to the story. Templeton is seen not making phone calls and then submits an incredibly worded quote. Haynes is again dubious about the material and asks Templeton for his source. Templeton reluctantly credits the quote to Nerese Campbell and claims that Twigg is not the only skilled reporter in the newsroom. Haynes accepts the quote for the piece.
Templeton is pleased when he is offered an interview with The Washington Post and takes the day off to attend. When he first arrives he is eager to observe a budget meeting but during the interview he becomes discouraged when his prose is described as overwrought and he is not familiar with the stories that have most impressed the editors of the Post. They do not offer him a position but do promise to keep his resume on file and ask him to reapply when he has more experience. Templeton returns to Baltimore disheartened.
Haynes asks Templeton to assist Bill Zorzi in catching them up on a missed story about a local corruption charges against Clay Davis. Templeton is assigned to contact state's attorney Rupert Bond and Haynes later praises his hard work in preparing the story in time for the next edition. Templeton admits to Gutierrez that he was unsuccessful in his job interview and reverses his position on The Sun stating that it is not a bad paper.
Haynes is briefly impressed by Templeton when he hits the streets and writes an excellent profile of a homeless man who suffers from PTSD after an IED hit his patrol unit in Iraq. However, Templeton also claims in the same episode to have checked on a fraud case, and Haynes later finds out his explanation for the story doesn't check out. The vet later comes in and says Templeton lied about his story as well, from saying they were in a Black Hawk Down-level firefight to saying they had coffee instead of chocolate milk. Haynes goes to the Walter Reed Center in D.C. and talks to a wounded veteran who backs up the interviewed vet, saying he's not a liar. Templeton continues to fabricate information for the fake serial-killer plan that McNulty hatches, and the detective quickly realizes Scott is a fabulist. However, in the end Haynes and Gutierrez both receive demotions for questioning Templeton's work, while he wins a Pulitzer Prize for his "reporting" on the homeless in Baltimore.
The character of Templeton is fictional. It does not accurately portray any real person or events at the Sun. However, David Simon has said in interviews that the character and his actions were inspired by several real-life cases of fabulism at the paper by unidentified reporters.
