Masters is annoying and we all know people like her. someone who is hung up on themselves and their upper higher than thou morals. but when it comes down to it, they will resort to the same tactics that House uses if its their loved ones. House walks the grey line between morals and ethics but he is concerned with results. Masters puts the results after her morals. Life is Life and as much as House is an a-hole he does his best to help his patients.
Also Taub is my least favorite character on the show but he got my vote in this episode for standing for his principles.
