Yeah, I thought that was a good Kirk episode, too. His eyes were spinning, really funny. And again we see how good and caring Luke is. He is always so gruff and says how Kirk drives him crazy, but he is always right there to help him out.
Although I did like season 4, I never did like Jason. I didn't like his attitude, or like Emily, that he wanted to go into business with Richard to tick off his dad. There were times where I liked Lorelai and Jason together, but you could always tell that they weren't right for each other. I didn't like the way he acted at all in that last episode. The way he refused to leave even knowing that it was an important night for Lorelai or the fact that he did lie to Luke, although I don't know if it was so much a lie as to he was just so sure of himself and thought that Lorelai would take him back. At any rate, I was so glad to have him gone.
