Patty's Transformation

Do you think the weightloss changed her? I only watched season one, and I know she does crazy things, and I know she still does in season two from watching seeing clips of season two. I feel the weightloss caused her differently because now she's skinny and she can do whatever she wants. Before the weightloss Patty wasn't really that kind of person, but we never got to fully see how she was when she was overweight. It was only when she lost all that weight that we got to see who she was as a person. She was hiding behind being overweight from people thinking she wasn't a terrible person deep down inside. Do you think Patty's weightloss changed her as a person, or do you think Patty was always this way?
