True reality shows don't have any scripts - they just naturally let things happen during taping. Because human nature is naturally unpredictable, it doesn't do your ratings any good when you can't predict the outcome.
So what you see on reality TV is not really reality. The producers naturally want to have drama and pathos so they will create situations where these things occur.
When you do reality TV, you're taking a risk that you will be loved or hated, depending on how your producer decides how to portray your character. You will make money but I'm not sure the risk would be worth it.
