Catherine was born in Sunset Valley. As a child, she found interest in astronomy. She thought that maybe one day, she could be an astronaut. Out of here siblings, she stood out the most. Catherine's brothers, Lewis and Ali, were not really serious when it came to fulfilling their dreams. If anything Catherine was a bookworm, studying hard for tests and did her homework everyday. Catherine grew up without a mother, as she died before she could even remember her.
Catherine didn't change much from when she was younger, but did work out often to prepare for her career.
After graduating from high school, Catherine enlisted into the army. She started at the bottom of course, cleaning latrines. Eventually she was promoted to squadron leader.
During her career, she met Walter Vice, a Spy that was on a mission to find a corrupt military commander. She help him complete the task by drawing in the suspect. After this, the two fell in love. Walter later proposed to her and the two were married shortly after.
Catherine and Walter eventually had a daughter named Rosa. Since Walter was busy with work all of the time, Catherine took time off to take care of her. She taught her how to talk, walk and potty trained her. Catherine knew that her husband was also an Assassin...head of the Sunset Valley Assassins. She often wondered if he would return home safely each night. Once Rosa was old enough to go to school, Catherine returned to work.
One night after a nice shower, Catherine looked outside to see her husband bleeding on the lawn. She called Rosa and the two rushed outside. Walter explained that Franco, an Assassin belonging to the same branch, had betrayed him and shot in the chest. Catherine could not understand why he would do this. Walter then told them that Franco was out to kill the Vice family, mainly because of their prowess as Assassins. He urged them to go into hiding and avoid the other Assassins at all costs. She kissed him, then Walter passed on.
