"Come on, ice cream was part of the deal, yeah?" she smiled over her shoulder but realized he had already lit up again and was all business now. Not that she had a problem with that, exactly.
Lavender pulled out her wand and cast a muffling charm before saying anything. "A list of potion ingredients, pretty simple." She pulled the list out of her pocket, glancing at it once more before handing it over. Most of the ingredients were volatile and that's why they were illegal, but some were simply used in dark enchantments. Lavender had no idea how often they were mixed with anti-psychotic potions to change their chemistry.
"The list is charmed to disintegrate by five tonight," she told him. Lavender wasn't always the sharpest cookie in the box, but she wasn't going to leave her hand writing asking for illegal substances around.
