Background
Gregory "Greg" is a resident of Amityville, New York. His mother is Kathy Lutz, his siblings are Amy and Matt, his step-father is George Lutz, his uncle is Jimmy, and his great-aunt is Aunt Helena. Greg's pet dog is Harry.
During the events of The Amityville Horror (1979) played by K.C. Martel
George, Kathy, Amy, Greg, and Matt move into the Amityville house.
On the 4th day, which is a Thursday, Helena shows up right when a smelly black goo starts to boil up from the toilets. Matt and Greg let Helena into the house and then run outside to play.
On the 6th day, after Jimmy's wedding, George, Kathy and Matt and Greg drive home.
On the 11th day, Matt and Greg are teasing Amy when Kathy catches them. The window slams on Greg's hand and George and Jeff have a hard time pushing thew window up. Kathy and George take Greg to the hospital and he amazingly doesn't have any broken bones.
On the last night, George yells for Amy and blood starts to pour from the walls and stairs. Kathy brings Amy, Greg and Matt into the bathroom and George starts cutting through the door with an axe. Kathy attacks George and he throws her down and strikes the axe toward her. He tells her that he wouldn't hurt her and the boards erupt over the well. George and the others run out of the house and into George's van. They start to drive off, but Amy tells them that she wants Harry. George stops the van and goes back to get Harry. He find Harry and they then leave the house, get into the van and George drives away.
Later, George, Kathy and their family never return to the house and now live in another state.
