When Sarah made her wish, she made a big mistake in that she left certain details implicit rather than explicit. As such, the power ended up working against her and in Lola's favor. As Lola laid down in shock, she found her thoughts becoming preoccupied with fucking, being dominated by a man, stripping, being sexy, and plotting her revenge.
Suddenly, she knew more about the stone than even her grandfather did... er, Jon's grandfather. She knew its capabilities, its limitations, and the exact locations of certain people who already knew about the stone. Furthermore, she knew exactly how to contact them and convince them to help her. She started laughing, a humorless laugh of cold rage. Sarah had ruined her life, so it was only fair to ruin hers. "Oh, yes," she said to herself, "There will be blood..."
But first, of course, she had to fix her makeup. And she needed a sexy outfit she could take off. Bloody vengeance wasn't going to pay for itself.
