Plot hole: When Evan is in jail with the religious prisoner trying to get him to help him get his journals back he goes to the scene where he is drawing that homicidal picture in kindergarten, but he gets up and puts the spikes that holds documents through his hands, creating a stigmata-style scar. The religious guy in the cell with him is so amazed because of this he thinks Evan is a prophet and he decides to help him. If Evan had gone back in time and got those scars on his hands, he would have changed the original timeline and would have arrived in jail with those scars the whole time. Some people try to correct this using the "If I can create scars, then can I fix them?" statement Evan made to defend the mistake and suggest he can create instant scars but he was using the word "scars" to refer to the negative events; not literal scars on his body. The scar he got when he burned himself in the past didn’t magically appear on him the moment he returned from the past; it became part of a new, slightly altered timeline (just like the scars on his hands should have been) and it let him know he can change history.
Jason Treborn: You can't change who people are without destroying who they were.
Question: I am confused about the second-to-last time travel of Evan where he ends up in the hospital/institution because he killed Kayleigh with the blockbuster. Since Kayleigh died after Evan began journaling (I remember Evan writing about being excited to meet Kayleigh's real dad), what happened to the journals that the doctor says Evan never had them? He must've had a journal with something written in it.
Question: This movie confused me. I know that when Evan blacked out was actually when he went back, but what I don't get is how he got back or why the hemoragging happened. I also don't get the whole scar thing. Wouldn't he have hemorrhaged from having the scars or is it only at major changes that he hemorrhages?
Question: Ok I'm guessing that Evan can travel back to "memories" an infinite amount of times as he has been to the junkyard and the basement memories at least twice, but what I don't get is why, after he saw the horrible repercussions of giving Lenny the shard which led to the psychotic brother's death, why didn't Evan just NOT give Lenny the shard, but still give the bro the moving motivational speech that made him rethink the burning of the dog? Then the dog would be safe and the bro wouldn't be killed traumatically, damaging Kaylee? Why didn't he keep that bit that seemed to work out, but not give Lenny the weapon?
