I love this episode. I teared up at the end when Dave was talking about his friend. I knew when he was talking that his friend had died. I think it brought a sense of realism to the show.
I thought it was very well written and dealt with the subject well. It was very shocking to have a character who had been in the background take center stage as he battled with disease. I think that what made the episode good was what happened to Rich was unexpected. The show served as important message to show the human side of a disease that at the time, many didn't understand.
