This storyline was already done. The episode with the African-American teenage girl and the record producer from new Orleans. House figured out he was the girls real father. This theme was also visted in another episode. House should have deducted the father-son relationship sooner. Repeating storylines is not very interesting.
House is still clean as a whistle with no explanation of his pain. Why does he no longer take Vicodin, why is nhe no longer in pain? Why is there no discussion of his pain. His limp is even FAR LESS apparent than previosu seasons. Drugging Cutty's mom and Wilson last week didn't seem to bother Cutty who has spent 6 years trying to get House to play by the rules. A lot of logic defying moments lately.
