As for Susan, she was the first to move away from Wisteria Lane. Before she left, she introduced herself to the woman who moved into her house. Susan then took one last spin around the block. She had a feeling she was being watched. As it turns out, she was. The ghosts of those who have been a part of her street were there, as they always are, hoping that the living will always remember that even the most desperate life is still so wonderful.
Of course, only the lucky ones realize the gift they've been given. Most people live their lives day after day consumed by their troubles and their secrets. This looks like it may be the case with the woman who moved into Susan Delfino's house. We see a distressed look on her face as she opens a memory box. We have no idea what's inside as the container is closed and hidden in a safe place. This woman is obviously hiding a secret. That's why we know she'll fit right in on Wisteria Lane.
