The idea of purity is underlined when Lizzie opposed resistance, and is compared with a lily,and a royal virgin town, because she remained "untouched" although they made her/tried to force her to taste the forbidden fruit. This thing looks like the temptation of Jesus in the dessert by satan when he didn't eat for fourty days. "One may lead a horse to water/ Twenty cannot make him drink".
But when Lizzie gets back to Laura, the way she calls her to "kiss,love,hug,suck her juises/Squeezed from goblin fruit" for her, or "to make much" of her, then the fact that Laura "kissed and kissed and kissed her" sounded a bit lesbianic to me. But maybe this shows the fact that young girls/people make mistakes in their youth, and somebody saves them, and helps them to get better and pass through that difficult moment in their lives, so they can tell the story to their children and learn from it....or maybe not, because Laura could have learned from the "experience of Jeanie" but she didn't,because she was tempted and wanted to have her own mistakes....!!!!!
