Courtney has also changed over the years. She has loosened up, shockingly. After Total Drama Island, her and Scott had a thing, but they broke up because she wouldn't give him any.
Courtney had an terrifying childhood. She went through things kids shouldn't have to go through.
Her family was perfect until her younger sister, Chasty died at the age of 6 from a sickness. Her mother was so depressed she started doing drugs. Her father tried but couldn't take care of her mother. He and her older brother left them. Left her all alone with a druggie.
Her life got better at the age of 14. That's when she started working and getting her own money.
She worked for everything she had. Her boss and work mates helped out with school and other things all girls go through.
Courtney life was boring until she met Duncan. Now that's she has him back in her life, she is not going to let him go so easily.
