I thought this episode was absolutely fanatastic, and certainly a Season classic. The episode focussed on the priest and his lack of faith, as well as addressing House's faith and issues.
This was probably one of the most interesting cases so far this Season, purely as the character development was superb with the patient. The writers didn't lose interest in him, and it was one of the first patients House connected with in a while. The acting and dialogue was electric in this episode.
House screwing Foreman and Thirteen around was classic as well, and it was an even better twist at the end when they turned out they were playing him.
The Cuddy drama was also interesting after a slow start, although the writers are annoyingly teasing us with the Huddy relationship. They really should make up their mind, as its beginning to get too soapy in that department.
Nevertheless, overall it was a brilliant episode, and certainly one of the stronger episodes recently.
