By the time Callie showed up in February of '93, Susan and Joseph Gibson had already decided how they would raise their children. Each with important jobs, they led their children into a life that they largely controlled on their own. It wasn't that they were bad parents, it was just that they wanted the kids to grow and find what they wanted on their own; they didn't want to push when unnessary. Callie and Felix, nearly as soon as she was born, were pushed together and made to look after the other. They were partners in crime, best friends. When no one was there for them, they were there for each other.

Callie lived what was meant to be a charmed life. When she was three years old, she spun her way into ballet classes at the Ballet Academy East. Though it took a lot of work, she was a natural and her mother would tell anyone that dancing was one of Callie's favorite activities.

Along with ballet, Callie grew up reading. Much of the time that she wasn't spending with her brother, she was teaching herself to read. Many nights before bed were spent adventuring at Hogwarts with Harry and the gang and it made her forget how sparce her parents really were.

In school, though she was smart, Callie was considered shy. She didn't like to raise her hand in class and she didn't like being called on. She was always respectful and her test scores showed that she was learning and paying attention, so the teachers treated her with kindness, instead of insisting she be vocal in the classroom. Her favorite thing to do was read but even then, Callie preferred to read to herself and got nervous every time she read aloud. She didn't enjoy playing popcorn, she didn't enjoy making up voices. All she could ever come up with were the words as she read them, feeling too slow and lifeless. It was a relief when she graduated to a grade where it was much more likely for the students to read to themselves.

In middle school, in eighth grade, Callie began to feel much more tired than normal. With the influx in school work and the fact that she had become a serious dancer, her parents chocked it up to stress and doing too much at such a young age. They tried to persuade Callie to cut back on ballet but to no avail. To her, ballet was the one thing that made her feel confident. It was the one thing that she loved doing in front of others. She felt good when she was dancing. So her parents didn't press. Fatigue morphed into nosebleeds, bone pain, shortness of breath, and fevers. For a while, Callie's pediatrician chocked it all up to the flu. Three weeks after first going to the doctor's, though, they went back. Her pediatrician still thought it could be something like mono, but they did other blood tests, as well.

When the tests came back with the title of acute lymphocytic leukemia, the family was floored. Callie didn't know what any of the words meant aside from the last one. It didn't matter what the first two meant if the last one meant cancer. To her pediatrician's credit, he got Callie an appointment with an excellent oncologist scheduled for the same day as the diagnosis. Thus began the longest year and a half of her young life.

First it was the radiation and chemotherapy to try to kill the cancer cells. Callie lost all of her hair, and not just on her head. No one mentioned that she would lose it everywhere and no one could have prepared her for it, either. She was constantly sick and, obviously, she had to stop dancing and going to school. Not being able to dance was one of the worst parts of having cancer. Her only friends were in her ballet class, where she felt she could actually be herself. Around this time, Felix started to pull away, leaving Callie without her partner in crime when she needed him the most.

Treatment after treatment brought hope and dissolved into heartache as the cancer would leave for a couple of months and then come back. She never felt 100% through the whole ordeal. Finally, they found a clinical trial being done at the Children's Hospital of Philadelphia. Susan and Joseph spared no expense when trying to see their daughter recover, and immediately sent her in for a new therapy called CAR T-Cell. They basically took Callie's T-Cells and genetically engineered them to target the cancer cells that kept coming back. When she was injected with her own modified T-Cells, Callie became very sick with fever and, thankfully, it was normal. It was, in fact, a sign that treatment was working. On the eve of Callie's sixteenth birthday, they got the news that there was no cancer evident in her body. She was cancer free.

Since going through the trials of cancer, Callie's trying to make herself stronger; she tries to appreciate each day and live it like she won't have another, which can be hard with how shy she is. She tries, anyway. Currently, she's twenty-one years old and attends Jeffrey Ballet School in New York City, where she's continuing to work to fulfill her dream of dancing with the New York City Ballet.
