The difference between Heather and Rachel is again the difference between the selfishness involved with the two characters. Heather is even worse then Gwen in that she is inherrently selfish and has no plans of being unselfish anytime soon.

Rachel's personality flaw is that her insane jealousy over Julia overritten her sense of moral judgement and while she was selfish and antagonistic at that time, she doesn't maintain that personality throughout the show. Heather, however, does and for the matter so does Gwen.

I actually see nothing in common with Heather and Rachel at all.
