Spoilers (somewhat) below....
I think the show can go on since they did a good job introducing new characters in the last few years. Mark's cancer came back a few weeks ago and he and Liz had a little breakup, she left with the baby but tonight she learned from Susan that he has 10 months max to live so she went back to him after talking with Robert (who was almost human tonight!) and encouraged her to go and stay with him. I missed the first 15 minutes of the show, so what was the deal with the college girls? Was it left to believe one stabbed the other? I was trying to figure out what the one that died whispered to Carrie... oh well. Next week I'll be out of town, I hope I can still see it 🙁
