@Diego, Most of us thought that she didn't get bunk beds because she was an only child, emphasizing her being "loneliest of all." Now I can't help but wonder why she didn't get bunk beds. Someone has suggested that maybe she didn't get to spend much time with Winter, being raised a little separately as heiress.
