the thing with the novaks is that they were set up to be exactly that: the average, all american dream christian family – which was the specific reason jimmy was chosen. because he was nothing special, aside from a good, devout christian. if cas hadn’t come along they had taken claire to soccer games, gone to church every sunday, run the bakesale and had family dinners every night. because they were created to be uneventful.

The only thing I’d argue with you on is that Jimmy was special – he could hear angels. Not even Dean or Sam could hear angels and they were the true vessels of archangels.
But yeah, they were set up to be just your average, all American family and thus kinda boring.
