It seems to me that they are playing house as a hard core socio-path this season. He only seems to care about himself...Prick
Hasn't he pretty much ALWAYS been like that?
Yup...just sometimes a bit more likable than at other times. This season the pendulum seems to be swinging in the "unlikeable" direction.
House is a great big douchebag. The writers have never really strayed from that, much to my amazement.
