"You're such a girl sometimes," she said in response and pulled her wand from her hair. It was a habit she'd never outgrown from Hogwarts and Rose could hide a dozen wands in her curly red frizz. "And are you doubting my brilliance? Need I remind you that am the brightest witch there is, aside from my mother?" She was teasing, of course. Rose might be a know it all from time to time, but she didn't (often) brag about her talent. "I had to modify a water repellant charm when I was in the Amazon. My hair swelled up so much that I kept getting it stuck on branches." And without and warning, she cast a spell at Scorpius. "I call it the duck charm." Water would roll off someone rather than soaking their hair and clothing. Rose thought it was rather ingenious even if it hadn't solved the problem of hair and humidity. Some battles weren't worth fighting.
