Brandon Carlile is a reporter for SPIN magazine who appeared in the Season Eighteen episode, "The Cissy". He is based on SPIN magazine reporter Brennan Carley, who wrote a widely criticized article about the episode, "Gluten Free Ebola", and its supposed implication that a middle-aged man, Randy Marsh, could pass for the singer Lorde.
Brandon goes to the Broflovski Residence to question Gerald Broflovski about a party that was held in his backyard the previous Sunday, where pop singer Lorde was the entertainment. Despite Gerald being unable to answer how the boys got Lorde to play at the party, Brandon presses him, asserting they deal with "a lot of fake stories at SPIN", and Gerald admits that Lorde is the niece of someone's coworker at the United States Geology Survey. Brandon takes the information and tries to track down the geologist, saying that it would be a shame if someone was having fun at Lorde's expense.
Tracking down Peter Nelson, Brandon asks him for any information about Lorde. Peter says that while he is not actually Lorde's uncle, he does work with her. He admits that Lorde lives a double life; when she's not singing, she's a talented fluvial geomorphologist at the US Geology Survey, who fills in for another part-time geologist. Connecting the dots, Brandon uncovers the true identity of Lorde, 45-year old Randy Marsh, and writes a tell-all article about it for SPIN. However, upon hearing Lorde's emotional new song "Push", Brandon decides against publishing the article.
Brandon Carlile wears a gray business suit, which consists of brown shoes, gray pants, a gray coat, a white shirt, and a burgundy tie with a gold diamond pattern. He has combed black hair and wears a brown hat with a "PRESS" tag.
