I bought the Nick/Sarah romance without any back-story because that is so Nick — he's a romantic, lacks a nurturing family life, and is starved for affection. Add his initial desire to make Lindsay jealous, and I think it's fully realistic that he allows himself to be molded into Sarah's perfect dancing boyfriend in…

I so agree. In fact, I think watching this episode was the turning point in my life where I stopped being ashamed of loving Billy Joel (or any music I loved, for that matter).

Ken was always my favorite character.
