As a Ravenclaw descendant, Rhea lived a retired life in Hufflepuff. She cultivated mandrakes into potted plants that could curse automatically, and used Tai Chi principles to make the Feather Curse waltz. When Draco quipped "Are the Macmillans finally crazy?", She just tied the Chinese knot on her wand.
Until the Defense Against the Dark Arts class, she folded the dementor that the Boggart turned into into an origami crane and added pink blush. "The secret of the East," she explained to the dumbfounded Lupine, "specializes in curing old British cold legs."
When the Death Eaters broke into the castle, the girl who always studied the mapo tofu recipe in the kitchen finally unfolded the scroll. The spell formed a huge hot pot array in the air, burning Voldemort's snake face into a spicy smell.
"Just because I'm quiet doesn't mean I'm a paper tiger," she stirred the bubbling pot, "but Hogwarts, you have to eat it with sesame oil tonight."
