Ron had been up in arms on her behalf when she'd seen him last week, and very pleasant to vent to, but a little too hot-headed. Hermione didn't think it would be appropriate to slip a love potion in Malfoy's food that made him fall madly in love with Filch, hex him, or turn him into a ferret. She didn't dislike the wizard that much, and besides, she was better than that.
