Her recent breakup had made things awkward with her former boyfriend's family; it wasn’t right to lead him on.  She had developed feelings for her best friend and was finally about to act on it when he announced his engagement. She was happy for him, sad for herself. Investigating the recent breakout from Azkaban was an excellent excuse to stay away. She told the boys to take a night off and enjoy the party, while she buried herself in reported sightings, hoping for a pattern to emerge. When the stag Patronus burst through the wall, she was up and running before she heard the message, "Attack at the Burrow, send everyone.’ She had torn out of her office, shouting for help.
