Ginny was stupid enough to try a love potion in Draco once. Fucking bint. After she found out about his Veela heritage, she decided that being Lady Potter wouldn't be enough. She wanted to be Lady Malfoy. But she didn't do her research. He was able to smell them. When he figured out who tried to give him love potions, he spoke to Hermione and she spoke to Harry. When he refused to believe her, she draged him to the goblins. Literally draged him by the collar. There he was examined by goblin healers. What they found made their blood boil and nearly caused a new goblin revolt. They healed him and got rid of the magical bindings. They introduced him to Parselmagic and got him in contact with the right people.
