Cassandra Booth

Cassandra "Cassie" Lane Booth (born Cassandra Lane Braxton) is a co-protagonist in the yet unaired Bones & Numb3rs fanfiction crossover series. She is the daughter of FBI Agent Seeley Booth and a main character in the first five seasons of Bones, before she transfers to Los Angeles, California and joins the Violent Crimes Unit of the FBI under Special Agent Don Eppes, where she remains a part of the unit for five years before transferring back to D.C to be closer to her family.

Early Life
Cassie was born to Krystal Braxton and Seeley Booth. They both tried their best to raise Cassie as young parents, but things were far from perfect. Cassie was three when her father enlisted in the military. Over the years, Krystal became a drug addict and Cassie eventually fell onto that path as well.

During her Jr. High and High School years, Cassie was using drugs and smoking and casually skipped school. Due to a lack of stable parental figure in her life. One night, Cassie nearly overdosed and was found by police officers who arrested Krystal. Seeley was alerted to Cassie's situation and took her in. Over the next couple years, Seeley helped Cassie get clean from her drug addiction and helped her get a job at the Jeffersonian Institute as a forensic photographer.

Personality
Growing up, Cassie learned at a young age to take care of herself which molded her into a fiercely independent person. She takes care of herself, even when she lives with her father. Cassie also shows similar personality traits as those of Seeley, in that she's protective over those she cares about and has a soft spot for children. Cassie loves her family dearly, and is close with her brother Parker, despite there being over ten-years age difference between them.

Despite her putting on a tough act and acting like nothing really gets to her, Cassie does hold some insecurities regarding matters of the heart.

Zack Addy
Cassie first met Zack when she started working at the Jeffersonian. After working with eachother for over a year, they grew to become friends and eventually have a romantic interest in eachother.

Lance Sweets
After her relationship with Zack ended, Cassie talked with Sweets about the fallout, feeling heartbroken and fearing she would throw away her sobriety if she didn't talk her feelings out. Eventually, Cassie and Lance grew closer and formed a romantic relationship. This relationship turned into an engagement, but was broken off in the season five finale of Bones.

Colby Granger
Colby was one of Cassie's partners when she transferred to the L.A Violent Crimes unit of the FBI. After working together for a year, their feelings grew from friendship to romance and they began dating in secret. After the reveal of Colby being an undercover double agent, Cassie distanced herself from Colby for a while, but eventually they agreed to a clean slate and started their relationship over as friends. Over the next three years, they fell back in love and moved back to D.C to work with the Jeffersonian team once more. Eventually, Colby and Cassie married and had a son they named William Booth-Granger.
