My apologies. I am not sure I understand the question. I will try my best though. There are 20 memories in total. There is no feature to replay the events, unfortunately. To use the "Fantasize" option, you have to have points in the characters faction. Yes, Sally does have an ending. It is during Jean's route. All the memories and endings are mapped out in the Walkthrough. I hope this answers some your questions. Thanks for playing!
