And I remember reading an article about the girl who plays Alex...something like her parents ride her HARD to keep her weight down, and it stresses her out to the point where she can't keep weight off and is getting bigger. Some shite like that.
I'm not 100% certain either, but I am confident in saying that it was her mother was abusive in controlling her eating habits and the actress was taken away from her.
Then being away from the mom, she started ballooning up.
I saw a few posts on Reddit about her. There's pictures of her on different weekends dressed like a skank at a farmer's market while chowing down on corn dogs, ice cream, cotton candy, and other unhealthy carnival-type food.
