Sidney found out from Roger before Benjamin killed him the reason he started the Ghostface society was because in the 1970's her mother Maureen dated his oldest son Roger Jr they were happy untill she found out she was pregnant and she aborted their child because she was too young to be a mother and didn't want the responbity of raising a child when Roger Jr found out he became depressed and killed himself. He vowed to make Maureen pay and he found other people who hated her and wanted her dead and they started a secret society.Someone suggested the killer should wear a black costume with a mask that had a Ghostface because it would make it more horrorfying for her since she was afraid of ghosts.He said there were many members of the group including her brother Roman who joined the group in 1994 one year before Maureen was killed.She asked did Mark know about this society? He said yes but don't worry he wasn't a part of the society and he didn't know who was behind it, all he knew that there was a group of serial killers who wanted to kill Sidney Prescott for one reason or another and he wanted to stop it.He said her teenage cousin Jill acted on her own she had nothing to do with the society. He said he came to town to tell her the truth because he was an old man now and just wanted the killings to stop too many innocent people had died and he was going to turn himself into the police. A few days later she went to Niley Crinkley's funeral and to a memorial service that was held for Brianna Albertson and Jessica Mitchell their bodies still hadn't been found in the rubble of the explosion. One week later Robert Morgan asked Sidney to marry him and she said yes.
