One of the consequences of Leigh’s disappearance is that she’s been forced to become more like her, in that she too now holds on to the past in the way her sister did. This hadn’t been one of her sister’s better traits. Leigh had been nostalgic, determinedly sentimental; she never loved something so much as the moment it was gone. This was a cheaper, more contrived version of emotion, standing in for more difficult truths; amusingly, it had become Leigh’s legacy.
