Possible spoilers, I loved the movie it was so sad but also thrilling to watch. As someone else said C.J. and Sebastian go back in time to save Calvin but then if Calvin lives Sebastian dies and vice verca. At the ending we see her running off but then it ends. One person said she is going to repeat the same mistake, but my theory is, she is going to sacrifice her self. Now this is stretched but one person said the life would demand another life for a life (like Sebastian for Calvin) but right before she jumps she says “I love you Sebastian” meaning she probably won’t see him again. So that is my theory. All in all the movie was great
