Also, how did the GNs contradict Isaac's story? *curious*

Oh oops forgot to answer this :$ Um... in the finding out about his power thing. The novels said he painted a girl that got hit by a bus which he had showing at an art gallery, but I believe the show said the bus with the number in the paper and whatever was going on there was the first predictive painting that he had done (or at least discovered what he had done).
