Today's a Big Day for Harry Potter Fans

If you saw more people than usual ramming head first into a wall at King's Cross Station this morning, that's because JK Rowling caused a bit of a stir when she reminded fans of a special occasion in the Harry Potter-verse, Vanity Fair reports. "Could somebody at King's Cross wish James S. Potter good luck for me?" she tweeted. "He's starting at Hogwarts today." That's right, Sept. 1, 2015, is apparently the first day of school for Harry Potter's eldest son. (As described in the epilogue of Harry Potter and the Deathly Hallows, James' little brother Albus won't be leaving the nest for two more years.) Rowling later tweeted another big reveal—James was sorted into Gryffindor. (More Harry Potter stories.)
