Despite years of isolation, Elizabeth has a free-willed, almost childlike spirit, demonstrated by her dancing on the beach in Battleship Bay and in her interactions with her surroundings. She is also somewhat mischievous, helping Booker to pick locks and liberate goods if the proper resources are available. She has a biting wit and sarcastic humor, calling Booker out on his missteps without hesitation. At the same time, she possesses an immense amount of reserve and determination.
