Mallory is the younger sister of Matthias and J-Fred, by about 18 years. So, you could say there's definitely a gap between them. Regardless, they have always been there for their little sister, and they always help her through tough times. Like when their parents kicked her out at 16.
Mallory was outed to her parents and that resulted in her getting kicked out. With nowhere else to go she called J-Fred and of course he said she could come stay with them. He even came and helped her pack her things up and move into their house.
Now that she had been disowned, she had to get a job, so she didn't feel as guilty about staying with her brother. Matthias was not the first person she called though; she didn't want him to give her a job just because she was his little sister. When he found out about everything though, he begged her to come work at Hi5 studios so she could be with them all day and they wouldn't have to worry. So, she became part of the Hi5 family.
