- "I’m proud to be the first Scout troop to achieve this rank. I’m also terrified to be the first Scout troop to achieve this rank. The two emotions are mixing inside my body and it’s confusing. It’s confusing."
Earl claimed he was nineteen years old for decades or more, until suddenly he was a middle-aged adult with a job and family, and no memory how he got to that point.
Harlan was one of the leaders of the Night Vale Boy Scouts until the events of Eternal Scouts. While a Boy Scout he ate a human being, for which he got the survivalist badge. He is one of the victims of the mute children, who drag him away, along with nine others.
Somehow, he survived the mute children, and as of Capital Campaign, he is the sous chef at Tourniquet.
Harlan was somber and self aware of his feelings, and conflicted between his terror and pride at the upcoming Eternal Scout ceremonies.
He has also struggled with becoming an adult and having a family, mostly due to the fact that he was literally nineteen years old for a long time and from there, suddenly became a middle-aged man. He is often confused by this new life and responsibilities, and he usually consults Cecil when he is invited to the show.
- Earl Harlan was Cecil Palmer's childhood best friend. They were in the scouts together and Earl taught Cecil a way to hook his phone up to the radio station while earning their 'Subversive Radio Show Host' badges. When Earl is taken by the scout children, Cecil says that he thinks often about the last moments he spent with him and the things that were said.
- In Homecoming, when Earl first makes a guest appearance on Cecil's show, Earl presses him for information when Cecil brings up a memory of their graduation party together, but Cecil refuses. Earl somberly tells Cecil he thinks they "have something".
- Earl has a wife, whose name is unknown to the listeners, and a son named Roger. After being 19 years old for many years, he woke up one day and discovered he had a family. He does not know his wife and son very well at the beginning, initially saying he does not know his son's name, and forgetting it often even afterwards. He later tries to connect with his son by cooking for him and watching football together, with limited success.
