After forcibly giving Katey a sedative at the house, Dr. Beck reveals that Slater had a son named Eric who was deformed and mentally underdeveloped thanks to an illegal fertility treatment he had given her. Dr. Beck uses Katey as bait so he can capture Eric and cover up his crime. Eric arrives and hacks Dr. Beck to death while Katey searches for Vicki's gun, which does not fire. She flees to the bathroom and finds Jeanie's severed head in the toilet. Horrified, she climbs to the attic where she is attacked by Eric, now wearing a clown costume. She shoots him repeatedly, only to realize the gun is loaded with blanks. She then uses a pin to stab Eric numerous times and he falls through the attic door to the floor below. Katey believes he is dead and rests from exhaustion. However, Eric opens his eyes as the film ends, leaving Katey's fate unknown.
