Danika likely is Fixated at the particular psychosexual stage of development.
In Freud's Psychosexual stage of development, the oral stage is a stage that involves an age range from birth to 1 year and the erogenous zone is the mouth. A child's initial source of interaction occurs through mouth which results in the sucking reflex which is important. Sucking and tasting are the major activities in this stage.
During the stage of development, some issues can arise in the growth process and if these issues are not resolved at the appropriate stage, it results into fixation (a continuous focus on an earlier psychosexual stage). When fixation occurs, an individual remains stuck in a particular stage. An individual when fixated at oral stage may become over-dependent on others or starts oral stimulation like smoking, drinking or eating.
Here, in the question, Danika is fixated at oral stage and hence she is continously smoking and chewing her nails.
