Jane is Jake's younger sister.  She's a barista at the cafe at Nugget's Computer Warehouse.

Jane and Robert used to go out when they were in High School but he broke things off for reasons that he is unwilling to discuss, even with her.  The two kept in contact throughout the years (Jake is a friend and former coworker of Robert).  She enjoys coffee and likes to give advice.  She's moderately level headed, speaks her mind, and isn't afraid to get things done. Jane and Robert are currently in a relationship and are seriously considering marriage, but no date has been set. 

She tries hard to keep Jake in line, with moderate success.

Jane was also a bit rebellious when she was in High School.
