The storyline was inspired by South Carolina.
Criminal Minds writer Karen Maser said the idea for the episode sprung to mind after seeing young brides-to-be on the town in Charleston, South Carolina.
"At night and on the weekends, it was hard to walk on the sidewalks without bumping into these groups of young women celebrating during bachelorette parties," said Maser. "Charleston is the no. 2 destination in the U.S. for weddings because it has over 200 churches in the city. The sight of these gaggles of happy women stuck in my mind."
