Yeah, purple hair kinda runs in the family......
They're siblings, Joey being the youngest and Zach is the oldest. Joey and Rachel aways get into arguments and Zach finds it hard to keep them under control, but he manages somehow.
Rachel usually refers to Joey as "the twerp" and Joey hates it and that's what usually starts the fights. Just normal sibling rivalry.
