Nina is considered an alcoholic partially due to her casual nips of alcohol during the day at work. Due to her former status as a supermodel, she has been plagued by an obsession to party all night long and to return to work the following morning with a hangover. She is also, if no longer an addict, extremely experienced in recreational pharmacy with a wide knowledge of (and access to) uppers, downers, mood regulators and hallucinogenic compounds (she is able to identify not only that a Chinese sweet "Lemon Wacky Hello" is a hallucinogen, but also its chemical make up, by taste alone). Her slow-witted and even foolish demeanor create a lot of embarrassing situations for her character. She is understood to be promiscuous and possibly bisexual.
