Jacob, watched by Melissa, is there in the front yard, watching the sky. He looks up and out, past the curve of the mountains that trap Alamogordo in a gravity well... his eyebeam keeps curving, and after a long period of time returns back to earth, allowing him to see the back of his head (no surprise there).
I wasn't a killer. I was a bee-keeper. There was only one way I could go.
