It can be clearly said that, unlike what some people say, the director is pretending to be B, or has left many loopholes unfilled. It's just that the analysis is not in place or some important details are ignored. As a newly graduated science student, I would like to introduce my own views, hoping to help everyone. Of course, if there is anything wrong, we can also discuss it with each other.
The real murderer is Catherine, a smart and meticulous bisexual psychopath.
1979 Catherine murdered her parents, causing the yacht to explode and die, becoming the heir of a huge fortune and narrowly escaping.
1983, two female college students, Catherine and Beth, got to know each other and conducted an experiment-making love in bed. Catherine fell in love with Beth and was crazy about it. Beth thinks it's just an experiment, ignoring Catherine's pestering and approaching their professor may have feelings. Catherine became angry from embarrassment, seduced and killed the professor, and the wicked complained to Beth first.
Beth knows Catherine's character. After graduation, she changed her name and surname and married a doctor in Salinas Hospital. After graduation, Catherine married the middleweight champion in 1984, and the champion died in a game in 1985, and she became a widow. I don't know if it has anything to do with her, but I think it must, because everyone around her will die.
1986, lonely Catherine found the news of Beth again and pestered her, but Beth was disobedient, which led Catherine to kill her husband again. The patrolman said Beth was a lesbian, and the other one was Catherine, of course. This is reasonable. If you think the evidence is not enough, here are more reasonable arguments)
Beth later opened a clinic with the psychologist of rock singer Johnny. However, Catherine still hasn't given up her entanglement with Beth. 199 1 year, she found Johnny, approached him intentionally, and became a sexual partner, during which she wrote a book about the murder of a rock singer. (Look at all the film reviews, this place has fooled a detail, that is, Catherine and Johnny have been together for a year and a half, while Beth will stay for a year, so the explanations of some film reviews are unreasonable. Actually, this is easy to explain. The first possibility: Catherine is looking for people around Beth and thinks Johnny is a good material. Then find an excuse or an opportunity for Johnny and Beth to meet. Catherine knows Johnny and his psychiatrist. Johnny's psychiatrist and Beth are colleagues. It shouldn't be difficult for Johnny and Beth to know each other, but such a seemingly simple understanding caused considerable disadvantage to Beth later. Visible Catherine's meticulous. The second possibility: Catherine lied. He has known Johnny for not a year and a half, but maybe less than a year. Johnny may have made up with Beth. Catherine continues to win love, seduce Johnny and kill him. That's possible. Different people have different opinions. But what is certain is that Johnny's death must be because of Beth.
Although Catherine and Johnny became friends, she also had an affair (more likely) or an interest relationship with Nelson. Because Nelson did two things during this time, one was to take away the record of Katherine falsely accusing Beth, and the other was to investigate the death of Beth's husband. It has been five years since Beth's husband died, and no one knows the false accusation on campus except Catherine and Beth. Nelson did these things, but Catherine didn't order anyone else. This also indirectly shows that Beth's husband was really killed by Catherine, and it was well transferred to Beth.
Catherine prevented Rosie's death. She knew that Rosie was jealous of Nick, but she still stimulated Rosie unscrupulously. She knows Rosie's nature and Nick's skills, so Rosie's death must be in her plan. Why should Rosie die? Because Catherine is a pervert, everyone around her has to die.
Three months ago, Catherine easily bought Nick's information from her old photo frame Nelson. Why are you looking for Nick? Because everyone Beth likes has to die, and she still loves Beth. In order to achieve the purpose of framing, Nelson also had to be silent. Of course, all the information has been passed on to Catherine.
When Gus died, Catherine found out that he was going to investigate the truth of their college life, so she invited Gus to a meeting under the guise of college classmates and left a message for Beth to go with her, so as to plant the blame and achieve the ultimate goal of revenge. (There are hints about Gus' death in Catherine's new book, but the protagonist is slow to respond, so I have to say that Catherine has a strong overall planning ability. Why didn't Beth leave a message on her cell phone? The reason is simple. The film says that the tape recorder has never been used, yes, it has been changed. It is not difficult to delete information when you have someone's key.
Finally, Beth died. In fact, Beth is nothing but two endings. One was killed by Nick, and the other died alone in prison. Of course, Catherine was responsible for her fate, and Catherine caused damage to her lock, which paved the way for the final planting.
Finally, why did Catherine cry? Of course, she cried for Beth. Beth is the woman she has always loved, but it's a pity that Beth didn't follow her. If she did, so many people would not die again. And why didn't Catherine kill the hero in the end? Because the hero can replace Beth now. If she kills the hero, she really has nothing. But we don't know if the hero will die in the future. This is also a daydream space for us, but I believe that after my above analysis, it doesn't matter whether the hero will die or not. It all depends on Catherine's mood.
