Stopping at the Shrieking Shack to catch her breath and enjoy some fresh air, she didn't know Fenrir was nearby until he stepped out of the shadows. She almost screamed and cursed him at the same time. Her reaction only made him laugh. Something in the air that night was different. Perhaps the heat went straight to her head. After standing alone with him for several minutes venting about the ineptitude of so many in their society, she had a crazy idea of how she could blow off some steam. Returning home to argue with Antonin wasn't a good alternative.
