Dumbledore and Grindewald sitting in a tree

J.K. Rowling outed Dumbledore as being gay during a Q&A session. Apparently he was in love with Grindewald. I never thought she would actually admit to one of her characters being gay, so it's kinda cool. See the Leaky Cauldron for the whole interview. It also says Neville marries Hannah Abbot who becomes the new owner of the Leaky Cauldron.
