Sally-Anne hopes that some of the treats in Higher Grounds will appeal to this foodie. Or the coffee after those sleepless nights! It's a mystery to both her and Parvati how anyone can be so grumpy.
(Blaise would have known her from school, I guess.)
I don't think any of the rest really know her.
Apart from Stebbins. Who, despite her crankiness, enjoys her company and doesn't think much of her boyfriend. He'll be sure to make his cat scarce when she comes to visit.
