chunk: After Dr. Loomis tells her that she is living in Michael's home, Debra calls John to tell him she wants to leave Haddonfield but is killed by Michael. Later, Kara returns home to find Danny in his room with Tommy, whom he had met while on his way home. The three go to the boarding house, where Tommy reveals that he believes Michael has been inflicted with the curse of Thorn by a Druid-inspired cult. Thorn is an ancient Druid symbol that represented a demon that spread sickness and caused destruction. To prevent this, one child from each tribe was chosen to bear the curse of Thorn to offer a blood sacrifice of its next of kin on the night of Samhain (Halloween). When the corresponding Thorn constellation appears, Michael appears. The curse explains why Michael is out to kill his family and also accounts for his superhuman abilities. Tommy believes that Steven will be Michael's final sacrifice.
