In the beginning, the character of "Nathan" was described as "cocky and an academically-challenged high school junior". In an interview Lafferty mentioned his thoughts on Nathan and Haley's unlikely relationship, "I think, to start with, the likelihood of the situation, of Nathan and Haley coming together, was so small. In our first few episodes, the characters were worlds apart. It didn’t seem like it would be a good fit. But sort of against all odds, they continued to make it work over the years and they fought through adversity. I think they’ve become a couple that you don’t take for granted because they’ve been up against so much. So you root for them. " "Nathan and Haley's fan base is so strong, and there's a reason for that. That couple is gold as far as I'm concerned, and I've felt that way since the very beginning. " said Mark Schwahn on the couple. At the end of season three, James Lafferty has said he enjoys playing the rebellious Nathan, which he believes is due to his upbringing and having a father like Dan. He said it's a personality trait he can relate to from his own personality and it's fun to bring it through to Nathan.
