So the theory that Emma's darkness will be the thing to kill her, and the theory that Lily is the hooded figure. They can both be linked: lily IS Emma's darkness.

So this theory isn't much, its just that the theme of oneself being ones own enemy (regina evil queen, jekyll n hyde etc) will mean Emma will kill herself and the idea that Lily will kill her will also occur, and there will be links between those two facts.
