Jacob's Older Sister
Katherine is Jacob’s older sister, CEO of ArithmeTech, and the whole reason Jacob still has his day job. Intelligent, ruthless, and a bit stiff, Katherine climbed her way up the corporate ladder until she could go no further – and she has no plans to step down any time soon. The only time she drops her stilted facade is around her brother. His constant prodding – she hates it when he calls her “Kitty Kat” – and his nonchalance irk her, and their interactions tend to devolve into childish bickering and name calling. She believes he is wasting his potential and that he should take things more seriously (especially his job) and has even offered him a position working with her at the company’s headquarters in New York. Despite their differences, she cares for Jacob, and him her, though you would be hard pressed to get either of them to admit it.
