Jeff Slingerland (played by actor Callum Keith Rennie) was a teacher of American history at South Fairfax High School. During the Global Blackout, he experienced no flashforward, and is thus a ghost. After the GBO, he joined Already Ghosts and became the Raynaud of a Blue Hand club in Los Angeles. He was arrested and interrogated by FBI agents Mark Benford, Demetri Noh, and Al Gough. Demetri showed Jeff a picture of a deceased member of the Blue Hand who was responsible for shooting Janis Hawk. Jeff ignored his questions and revealed no information as to who the man was. Demetri wanted to question Jeff some more but Mark knew Jeff wouldn't talk as he had nothing to lose, because he knew he was going to die soon anyway. ("The Gift")
