Frank's story was also great. I wonder if they did it because the viewers started to dislike Frank. He kept on making some pretty bigoted comments and unlike Romano who was also a bigot wasn't as funny. But this story with his heart attack gave him lots of humanity. When we see the kid he adopted we see him as a man with a heart. And it was also sweet to hear how he always has stories about his work and thought highly of Neela. Frank is now a better man in my eyes and in many viewer's I am sure.
Well, I have an issue when people say they want casual relationship and then get mad if the person who they told it to follows it. So I see no reason for Sam to be mad at Luka. I didn't like Gillian, but in this story she is the only one I felt bad for. At least Sam didn't keep on being nasty to Luka about it.
