I wouldn't say that I'm very similar to the character of Nathan at all. Both of us have had very different upbringings and backgrounds. I have a competitive nature like the character of Nathan. That's really easy to draw from when I'm acting; that's probably the biggest similarity.
Although we hardly see each other off the set, Joy and I get along well when we do. As far as the marriage between Nathan and Haley, I think they are young and will see the reality of the situation eventually.
