In the cramped carriage, the platinum-haired brat across from me was taunting the redhead in an operatic drawl. “...What do you think, Weasley?” Rubbing my temples after a late night at work, I said, “Yeah, I suggest you two fight it out.” Before I could finish speaking, my fingertips tingled. A tiny glimmer burst out of control with a pop. Did I really have magic?! Draco recoiled in shock. “A Nonverbal Spell? In first year?!” I stared at my fingers, glowing against my will. The laws of physics shattered before my eyes.
