Dex Langan

Dex Langan was the original name of a visitor to the Inn in 2006, who was transformed into Kayla Johnson. Dex was an FBI Agent tasked with investigating the Brewers at Augustfest to see if any of them were distributing their products to underaged drinkers. One of his previous assignments was to infiltrate a Nation of Islam prayer group, which he describes as unsuccessful. He was a graduate of the Bureau's Milton School of undercover training. He had blue eyes, brown hair, and a love of outdoor sports.

After the transformation, he became Kayla Johnson, a 22-year-old woman. She was a graduate of the University of Wyoming with a degree in Wildlife Management, and was due to start work for the National Parks Service in the fall, before being transformed.

When contacted by Jessica and Louisa during their road trip, Dex revealed that he had not been in Maine to investigate underage drinking, but to gather intelligence on a supposed conspiracy that involved the Inn. He was still working on the case during his time as Kayla, showing Jess and Louisa a bulletin-board-and-string diagram linking various people who had been to the Inn. However, he did not believe it was a plot to replace people in government positions, as the agents resigned as often as not, and what appeared from the outside to be corruption was more likely to be mere incompetence when the Inn's curse was factored in. His working theory was that someone, code-named Pygmalion, was simply "screwing with people" to see what would happen.
