Probably the reason that Leshawna accepted Heather's shoulder could be that because of the spa incident, Heather and Leshawna find that they have more in common than the other believes. Heather sees this and is therefore willing to see Leshawna in another light. This seems possible considering how she used to see her back in season 1; a kind, sweet, compassionate individual to stood up for other people and offered a shoulder to cry on. This, I take it was one of Heather's petpeeves and therefore refused to accept Leshawna for it. When she heard the insult about her on the hidden footage, instead of getting angry and trying to get even, Heather simply let it slide. She told everybody that Leshawna was just telling it like it is and that there was nothing to get worked up about. And since she does that sort of thing all the time, Heather is used to that kind of treatment. She basically likes anybody who is as mean and nasty as she is. That kind of thing puts Heather under some sort of spell, telling her to be nicer to those people and to go easier on them. Bridgette was not too fond of the new Geoff, but Heather said that she was proud of him, which is something you don't often hear from someone like her. I wonder if she heard that little clip of Geoff saying that she was the hottest girl on the show. That might be why. And yes, Courtney is a total and complete sham. Not to mention a hypocrite. She may be twice as nasty as Heather, but they probably don't get along so well because Courtney goes way off the deep end.
