Okay, really and truly, you need to read "The Darkest Hour" before you read "The Gravity of Love". Going for the quick fix of the short little POV one shot is going to absolutely RUIN "The Darkest Hour" if you haven't read it yet. And it will also totally ruin the effect that reading "The Gravity of Love" will have on you if you haven't read "The Darkest Hour".

So go back. Don't ruin both stories for yourself.
