The following is my review of the context of the film, as well as questions and conjectures.
Regarding the parallel universe, I don't think I need to say more to the students who have seen the butterfly effect.
a: The fire at Sam's house led to the death of Janne. Sam jumped for the first time after Janne's death. He saved Janne but his parents died, so he returned to the world of b.
b: The brothers and sisters depend on each other. The girlfriend in high school died unexpectedly. Lonnie is suspected of being the murderer and has been imprisoned. Sam encounters Goldberg because of some chance (should be in college) and learns the butterfly effect and uses it to help the police handle the case. At this time, Elz Find Sam, say Lonnie is not the murderer, take out the diary and ask Sam to find out the truth. Sam goes back in time, while Janne goes back an hour before the murder and kills Reb and Elz. Sam saw two female corpses and returned to the c world.
n: Because Janne kept going back and killed all the women who might have a relationship with Sam. In fact, after Sam returned from world b, it was no longer world c, so let's call it world n. Sam found the crippled Linnon and learned that the murderer was someone else, so he decided to jump to the day Anita was killed on September 5, 2000, but because Janne went back to killing the witness Lonnie earlier than him, history changed, So Sam did not return to the n world, but to the o world in 2000, was discovered, regarded as a pervert, and returned to the p world.
p: Goldberg disappeared and Sam went to the bar to flirt with Vicki, but maybe something happened later that annoyed Janne, so Janne came back and killed Vicki, so actually Sam went from o world back to q world. Sam, suspected of killing Vicki, was arrested, stole the crime file before leaving the police station, and returned to the East Depot on September 19, 2004.
Question1: After he went back, he returned to reality without encountering anyone or making any changes, but the situation was clearly no longer the q world, well, it was the r world. Does it mean that Janne made other changes during the period that caused the two to return to the r world?
r: Janne went to work, so Sam went to the East Depot again, was arrested by the police, released after gaining trust, and found Goldberg's flowers at Janne's house. At this time, Goldberg should have realized that Janne killed those people, but Sam thinks Goldberg is a murderer. So back to the time when I went to the East Depot and found that Goldberg was killed, this time is definitely not in the r world, it should be when Janne found Goldberg's flower and went back to kill Goldberg's s world.
s: Sam met Janne and learned the truth, so he went back to being 15. Don't save Janne, go back to the t world, the world at the end of the story, Seb was found on two boats, Sam and Elz looked at each other and got married and had children. Except for Janne's death, everyone lived a normal and peaceful life.
Question2: Continue to jump back to the time of the 15-year-old fire without going back to the real time?
About arson:
The last time the ending went back to being 15 years old, the fire alarm was broken, so someone must have set the fire on purpose.
The key is who set the fire?
I always thought it was Sam who set the fire.
Maybe 3 is the same as 1, and there are several endings, one of which is that Sam is trying to trap Jenna in the house and the two are burned to death together.
Like the tree structure, there should be a big branch where Sam's house is not on fire, and something in this branch caused Sam in one of the worlds to return to 15 years old, set fire, and opened the branch of the fire. The above a to t worlds are derived from the big branch of Sam's house fire.
So I can't understand where the little Janne burning the doll at the end and the expression that doesn't match her character come from. I can't accept the setting of her going back to kill her aunt, or the reincarnation of Big Jenna.
