In other dimensions Savannah would not be dealing with depression. Savannah wouldn't be planning to kill herself at the end of next month. In other dimensions Savannah wouldn't have met Charlie. In other dimensions Charlie would be trying to talk to Savannah because she's beautiful. Because her eyes would lead him to deserts of mountains and amber. But in this dimension he's not only talking to her because of previous reasons, but because of a moment of vulnerability where Savannah reveals she want's to die. In this dimension Charlie shows her the world from his eyes. Hoping he shows her that life isn't all black and white and sometimes all you need is to look for the color in a moment of darkness.
