On February 14, if you clicked on the 14, the Bloomsbury calendar counting down to HBP revealed a picture of Harry's name and a heart with an arrow carved into wood. In the area where a girl's name might have been carved, the picture faded to dark, so that you cannot see if there is a name there or not. Perhaps a tease of romance in HBP?
