You can say in a way that he tried to mirror Neil and Lynette's story with MC and Jill. I bet that her family will be strictly against their relationship, due to MC's apparent low-class upbringing, which is another cliché by the way. It is a common misconception that all aristocrats are snobs that look down upon people, which is not really true. I had a classmate in university that was of aristocratic roots (multiple generations of his family were painters and some of them were involved in the theatre business) and I can honestly say that he was a pretty normal guy, didn't show off and was down to earth.
The problem I have with Jill and her storyline is that nothing really makes sense in it. Her character changes depending on the storyline she's involved in, like she went from all out standing up for MC against Chad to a pushover that was being played by the saddest clown on the campus.
