|Family||Randy Meeks (older brother;deceased)|
Martha Porsche Meeks was Randy's little sister. In Scream 3 she is seventeen years old and lives in Woodsboro. In a way she fills a void Randy left in Dewey and Sidney after his murder and therefore they treat her like a close friend.
She snuck onto the Stab 3 set to deliver a videotape Randy filmed to Sidney, Gale and Dewey, shortly before his death, where he explained the rules of a horror movie trilogy to them in case he shouldn't survive the second killing spree, something that he had feared because of having lost his virginity. Randy had feared a third killing spree might happen, too because of his knowledge regarding these matters. He had given the tape to her sister for that eventuality, so that she would show it to them in case of such an event.
They thank her for having shown them the video and say goodbye to her. She then returns to Woodsboro but not before telling them her wish to see them back someday there.
