Sometimes the death of your favorite fictional character can feel just as tragic than the death of someone who is actually real (it's not, but it can feel like that), and no one knows that more than Harry Potter fans. Like a vengeful literary God, Harry Potter author JK Rowling killed characters off as easily as she wrote them in, ripping hearts from the chests of loyal Potterheads and stomping on them one thousand times. To try to make up for it, she agreed to tweet an apology for a death every year on May 2nd, the anniversary of the Battle of Hogwarts. This year, she tweeted in remembrance of Remus Lupin.
