I thought it was a GREAT finale!
I like the idea that Rex might still be alive, but I kind of doubt it since, when any publicity is done regarding the men of DH, he's the only one absent.
The whole Edie/Susan exchange ("Stick it up my what?") had me howling. And, again, Eva Longoria stole the show with her uppidy theatrics. I love her character.
And yes, I do think Mike is Zack's/Dana's father as well.
I'm gonna miss the show this summer...
