Dr. Stephen Gregory was a biology teacher at Sunnydale High School. He stood apart from others by having a genuine care and concern for his students. When Buffy Summers arrived at the school he was one of the few teachers that actually put aside her bad school record and saw a good student in her. Sadly, before he could really begin to nurture that good student he saw, he was murdered and raped by a she-mantis who left his body in the fridge in the school cafeteria.
