In learning to let Lee go this season, Cathy has decided to live life to the fullest while she still has it on 'The Big C' (Mon., 10:30PM ET on Showtime). In this season finale, that meant picking up Lee's plans to run in the New Year's Eve marathon.
She actually wound up picking it up quite literally, as she missed the deadline to enter, and took his number and ran it as him. But while Cathy was training for and running the marathon, she was missing some pretty serious stuff going down in the family, and this time it didn't involve Adam. In fact, Adam seems to be getting himself together.
