Williams, all her life, has been treated as a “woman”, meaning men looked down on her and wouldn’t treat her equally. One reason she decided to enlist for the army was to prove to herself that she can do anything. In her relationship with Rick, Williams feels betrayed when Rick told her that he’s married. From here she decided she had to change herself, and push herself to her boundaries. However, despite his marital status, Rick gave Williams a lot of confidence in herself, again pushing her to do something she didn’t seem possible. She had been using drugs and acting like a punk from a young age, so enlisting for the army was something completely opposite to her previous actions. Williams could have chosen any other course of action, but enlisting for the army made sense, because she realized that in order for people to stop controlling her, she had to be in control, and nothing gives a sense of self-control like the army.
