Even though our ratings numbers are still comparatively large against the competition - what's going on with the continued decline in targeted market?
3.5 for a much hyped/much anticipated episode coming off a two week hiatus? (for Pete's sake Glee got 3.6).
 
17.32 M viewers? that's the lowest all season

I have to say, I am really surprised - I thought the numbers would be huge...
