in Cholla Springs, New Austin
Almost nothing is known of Millicent's background. However, she admits to Marston that she once kissed a boy that she was not betrothed to. Also, her uncle would get drunk and grope her.
She is the first person to be located in the Side-mission "Missing Souls", which serves as an introduction to the Missing Persons activity. She is found trapped in Pleasance House, which has been surrounded by an undead horde, and terribly frightened. Upon seeing Marston through the window, she shouts for his help, and, with a cry of "Hey! Stop that! Now!", Marston kills the zombies surrounding the house. She must then be returned to Fort Mercer.
- At 15, she is the only minor besides Jack Marston, at age 16, and Miranda Fortuna, at age 13, to appear in actual gameplay.
- Her mother is the same woman who was raped in "Spare the Rod, Spoil the Bandit", complete with the low-riding V on her shirt and even the bruises on her face.
- Despite the fact that she needs to be rescued during the side-mission "Missing Souls", she appears in Fort Mercer, being aided by Dieter Frommel, when Marston first arrives. This is explained, however, when Marston questions why she was out of Fort Mercer despite having been in there when he first arrived, and she reveals that she had made a run for the nearest town, in order to find some food, because the zombies surrounding Fort Mercer have made food scarce.
