occasionally would leave Calliope home alone if she didn't want to come with him to hangout, leaving Calliope with a fear of the dark that Wyatt still apologizes over and over to her for to this day. Eventually, a few years in the future, Benji and Wyatt became partners and Benji moved in with them. Benji immediately liked Calliope as he was great with kids, though it took Calliope a while to get used to his presence. She eventually warmed up to him and liked his company, as the house felt less lonely. This would also give Wyatt an opportunity to not leave Calliope home alone, as he had a job with demanding hours.
When she was around 14, Benji decided to become a soldier. This meant she would be home alone from then on, but she didn't have as much of a problem with it, as she had friends to hang out with at school. But, when she turned 18, Benji quit. While this was happening, Calliope's half-sister was born.
At age 15, Calliope's half-sister, Mini Brie, was born. Mini then completed their family. Mini was (and is) a very energetic kid, a bit much for the more reserved Calliope. They still got along well, though Mini was a bit much for her sometimes. Calliope likes to do little activities with Mini, especially things like doodling together.
