"Oi! Paulie!" Zada heard a cockney voice calling from a few aisles behind them. "Paulie! Where have you been, Mate?" the voice called again. She heard approaching footsteps. The child's trophy, it appeared, had a friend, and she was about to be discovered. Zada had no idea why she was doing it, but she rounded the shelf and came forward into the main aisle of the bookshop finding herself almost nose to nose with the unsuspecting wizard.
He looked at Zada, and she could see that, had it been capable, his eyes would have bugged out of his head. "Well, well, Beautiful, where have you been all my life?" he asked, standing still, looking totally captured by her eyes.
Zada wasn't good at relationships but she was good at seduction. She turned on her best smiled, and she saw him melting in front of her. The pick up line, though was old and cliche. That really was a killable offense. No one should really be able to use those old lines anymore, Zada thought.
"And imagine me," she gushed in false flattery, "finding someone as handsome as you in this natty old bookstore. Forgive me for being forward, but..." She leaned forward and placed one slow, seductive kiss onto his lips silently, as she pressed her wand into his chest and fired, nonverbally, the Avada Kedavra into his heart. He fell like a stone at her feet. She turned and stepped over him and walked back to the child and her quarry.
"Always look out for backup if you're going to do something like that," Zada told her quietly. She folded her arms, leaned back against the bookshelf and lazily crossed one elegant heel over the other. "So what exactly shall we do with him, then, my young prodigy?" The girl had enough potential to impress Zada, and nobody impressed Zada anymore. That, in itself, said a great deal about the student in front of her.
