It's been a while since Criminal Minds ventured into the world of the occult, and the latest episode, Season 4, Episode 4, reminds us exactly why these episodes can be so chilling. They lead to some of the most creative and grisly MOs, making some of the most memorable scenes in the show. Alongside the gruesome case-of-the-week, this episode finally and firmly puts the season's overarching antagonist on the BAU's radar, as the cat and mouse chase for the Fan begins, but the case is like nothing the team has dealt with before. The Fan may just seem like another copycat killer, but with his idol alive and imprisoned, Elias Voit (Zach Gilford), the rules of the profile have changed, and the stakes have just gotten higher.
