Following the release of a video of Kate intoxicated at a Vortex Club party uploaded on YouTube, news of it eventually reached her family. Whether or not Kate's sisters were made aware of the video, is never explicitly revealed.
When Max is in Kate's dorm room and she finds two photographs of Kate with her family. Sitting on the shelf of her table is a picture of a Kate with her sisters, Lynn and Kate at the forefront, while the other sister stands behind them eating ice cream. Sitting off in a corner on a shelf is a picture of Kate with her sisters and parents. Kate's other sister stands to the right of her father, while Lynn is in the middle. Max calls them "the all American Zombie family" based on the mood of the photograph.
When Kate attempts to commit suicide on the girls dormitory rooftop, Max will mention her sisters as a way to bring her down from the ledge. However, Lynn is used as the means to convince her not to kill herself.
- Kate's sisters and her father are two optional dialog choices that are thought to be the deciding choices on whether or not Kate will attempt suicide.
- Max's dialog when referencing Kate's sisters may differ depending on whether or not the player looked at the photograph of Kate with her sisters.
