I think Sean is the most interesting character. He has strong values, but can be tempted like the rest of us. He seems to be a serious "family man" who wants a home and family. He is often frustrated with other people's lack of morals, and tries hard to stand up for what is right. On top of this, he is very good looking and his sensitivity and compassion for others makes him even more appealing. He seems like a real person, as opposed to Christian who is so superficial and selfish. Without Sean, this show wouldn't even work.
