Out of 179 total votes, "George Foyet was the Reaper" won out with 60 votes, or about a third of the responses. For those who may have forgotten: The Reaper was a major villain who haunted the BAU team in Seasons 4 and 5 and had a personal grudge against them. He was first introduced in the episode "Omnivore" as an unidentified subject with a long list of kills, one that Hotch (Thomas Gibson) failed to catch many years earlier. When he begins killing again, the BAU is back on the case.
To get a lead, they interview the sole survivor of the Reaper's original killing spree, George Foyet (C. Thomas Howell). The episode's twist is that all those years ago, Foyet stabbed himself and pretended to be a victim, when in fact he actually was the Reaper. When he attempts to fake his own death in the present, the BAU figure out Foyet is the Reaper, but he escapes them. He returns in later episodes to wreak havoc on their lives. All in all, it was a pretty slick plotline that made for a thrilling episode and set up one of the best villains of the show.
