How about the fact that Mitchell almost murdered someone. In his meet cute with Nikki he tells a story about how he used to be a bully on the waves and runs over a kid with his stick. The kid almost dies and is permanently scarred. It is the reason Mitchell is so Gandhi.
Shouldn't there have been criminal charges and a civil lawsuit. Who is paying for this victim's medical expenses? I think that is why his parents are shipping him off to Cincinnati. They don't trust him on the waves of Australia to not kill someone.
