I was rewatching Steins; Gate and i just watched ep24, in that ep Okabe makes it seem like Kurisu is dead but she isnt, so that the past wouldnt change, but if Kurisu wasnt actually dead, then wouldnt that mean after ending those 3 weeks when Okabe returns to beta worldine Kurisu would be alive? And that would result in Suzuha never coming back from future?
