The entire Chevy Chase storyline was handled terribly, imo. It seemed like they were at first going to go in a direction as if he had been with Saul way back when but then they changed their mind and wrote a silly way to get him off the show quickly. Who would go to a wedding and smoke a bowl? Especially at a woman's daughter's wedding whom you just got back in touch with after 40 years? And then when she got mad at him he seemed shocked and left.......what was he expecting? Her to be perfectly fine with it?
I loved the way they've brought Scotty back into the fold, definately my favorite recurring character. As someone said he just seems so happy and full of life. I hope Kevin gets his act together and things go smoothly, though I doubt they will.
As for Kitty and the senator.........I can't stand Rob Lowe so I'm all for their relationship to end. I however don't think they'll get divorced for at least a couple seasons if at all.
