Fiona had tried to deter the group of Muggles in the courtyard without much luck. She was now collecting her belongings, wondering how Rosier's group of men were going to deal with the Muggles. Fiona thought about how aggressive her approach had been and frankly, she wasn't going to stress about it because if her family found out that she had shown the slightest bit of kindness to Muggles, who knows how they'll punish her.

Was this a turning point in Fiona's personality? Maybe. Definitely.
