Jamie + Cornelia
When they are at the restaurant, doesn't Jamie basically threaten to blackmail Cornelia if she does not talk her dad into contributing to Jamie's film? He said something like their kiss "could be misconstrued" if other people heard about it. You can tell Cornelia realizes what's happening, but then the scene cuts to Josh standing outside the restaurant.
Why wasn't Jamie's threat a deal breaker? In my book, that moves him out of "a*****e" territory and straight into the "evil" category. But this incident doesn't have any consequences. Cornelia still seems to excuse Jamie's behavior and even defends his movie a bit when Josh goes off on him at Leslie's ceremony.
I don't understand why that scene didn't effect things more. I would think that after it, Cornelia would have cut off all ties with Jamie & encouraged Josh & Leslie to do the same.
