Except....he doesn't? That's what's so jarring about that line and that whole library scene. If anyone actually read Dicken's Great Expectations, they'd find Alison's statement odd, because it doesn't happen. That's not how the novel ends. Alison lies to Emily about the end of the novel, just like she lies to her (and everyone else) about everything. That scene is supposed to be indicative of Alison's manipulative nature. She seduces Emily in a way that is so cunning and sick it's borderline sociopathic. In that scene, she pulls Emily away from reality by offering an idealized, romantic, pretty picture of herself, just like she offers an alternate happy ending of Great Expectations. In Alison, Emily sees promise, but reality is, there's nothing there. It's all shine and no substance. If you're going to try comparing Emison to Estella and Pip....yikes. Because the fact of the matter is, Pip and Estella didn't have a happy ending together. Therefore, if you're going to look to Alison's statement as hope and proof that Emison is right for each other....think again. So when Emison shippers use that library scene as "proof" that Alison has "always loved Emily" and that Emison are "relationship goals!1!1!1", they fail to realize that the foundation of their relationship is based on lies, deception, and corruption. Alison never loved Emily. She loved how she could manipulate her. There's a difference.
