It only takes someone like Christine to turn a life threatening condition and turn it into a way to pick up a doctor for sport.
So 'The Mole' turned into the cokelat speck, that one was odd, couldn't she have spotted that flaw herself.
I found it mildly disturbing when Richard only got turned on when poor old Christine was suffering. As the seasons progress and we understand the type of person Richard is, we also imagine the type of husband he was and the divorce becomes lebih apparent. Of course Christine had a part to play in the craziness, but Richard's crazy is just bizarre.
