In the recap of her Iron Man, her dad comes on camera and says that it was "the happiest day of his life."
Just... so disturbing. I cannot imagine my family saying something like that. Perhaps the day I marry my beloved partner, or something, but completing an athletic endurance event? THE HAPPIEST DAY OF HIS LIFE? This man has serious issues. I am fascinated by how much he both talks down Nutty like she was sooooo unfit in the past and how much he venerates running and endurance events.
I also believe that completing races like this--time-consuming, all about the Iron Man label--can be a magnet for narcissists, and Nutty certainly fits the bill. And I must wonder how much of that comes from her deranged dad.
