I believe Cyrell and Jess were angry that at one point or another, Nick and Mick wrote, "leave", so they painted them in a bad light for their families. Cyrell knows that her brother is a hot head, and yet, she informed him that Nick didn't have her back. Jess insisted on bringing Mick home so that she could make him feel uncomfortable in the presence of her family. On Season Seven, several participants walked away, so their partner had no choice but to leave. I think Mick, Billy and Nick should just bail.
