The way Jason played the flop/turn it's tempting to put him on a flush draw, but I think he'd usually bet the river when he hits. But then again, he likes to trap people and might have decided to let the clueless guy fire at the pot again. The only other hands that makes sense for him are AK or AA. He won't play a big pot with one pair though, so if he does have this you should be able to move him off of it by showing aggression at any point in the hand. I think you may have been better off raising the turn.
