Not creating excuses for the change in the character of Dustin, but look at it like this. He was the way he was in the first season because he had a legitimate reason to feel like an outcast and was picked on in a few episodes due to his lack of front teeth. Now that he has teeth his demeanor has changed because in his eyes the only reason he was an outcast and/or not liked by girls was his lack of teeth so now he has all of this unjustified confidence which (SPOILER ALERT) didn't work out the way he had hoped.

Dustin was more of a focus in season 2 because of his popularity in season 1, unfortunately focusing on him did make it seem like a personality shift a bit, but I was never bothered by it.

I personally love the weird triangle of Steve, Jonathon, and Nancy. The show keeps pushing Jonathan and Nancy together, but I really like the way that they have never given us a reason to hate Steve.

And Back on topic the Lucas figure looks like a young Whoopie Goldberg...
