Kinzie is introduced as a socially awkward young woman who is antisocial, witty, sarcastic and mock-serious. She is very lighthearted and youthfully cocky, mentioning that she finds the Deckers too easy to hack. Being an agoraphobic, she doesn't venture very often from her warehouse on her own and in the case that she does go out on her own, she goes out with other people. After the Deckers have been disbanded however, she overcomes her agoraphobia and goes out for pancakes in an attempt to be normal.

She is very paranoid about various things, but is at the same time right many of them.

Kinzie has a habit of invading other people's privacy. She can have a violent temper, punching The Boss for mentioning the poodle skirt she was forced to wear, and assaulting Cyrus. She demonstrates a high level of intelligence as well. Kensington also demonstrates a softer side to her personality at times.
