Liz woke up early because she was the owner of the Underground. Her job was to make sure that the place was ready for whoever and whatever came to the Underground everyday. She was good at her job. This sanctuary was important to her. She wouldn't let anyone destroy it for any reason. For many people it was the only safe place they had. She might look and sound fragile but she wasn't. She was powerful enough to keep this place from becoming the war zone the rest of the world had become.
