somehow Chloe would die because the whole message about the game is that you can't change fate without consequences, the universe kind of stated that Chloe should die and it tries to kill her in any way possible. If Max would have died at that place, well she would just die. And Chloe would die at some other location. Just think of it, how many times Max saved Chloe from death. And always, as she changed something the consequences got worse and worse at some time Chloe would have died, in my opinion, regerdless of how much Max tried to save her, because the universe would have sended something that would have been even worse than that tornado. But that is just my opinion.
