Last week, Shawn disappeared from his home on 'The Big C' (Mon., 10:30PM ET on Showtime). While he doesn't return this week, a near-scare with a dead homeless man makes Cathy panic about losing the people she cares about. And since she can't do anything about Shawn until he's found or returns, she turns her attention to Lee.
While she's had a good response to the treatments, Lee's body hasn't responded at all and he's progressing toward death with his cancer. Meanwhile, Cathy found out about Paul's scheme with Myk to make money on the side, and therefore uses some of that ill-gotten gain to get Lee a ticket to Germany.
