I think so. He may easily have a hand like AQ, 22, maybe QJ. KK and QQ and KQ are also in his range but I dont think he would bet just 2 dollars on the flop with these hands, I assume he would want to start building a decent pot. That 2 dollars flop bet looks like he caught a piece of the flop but he doesn't like his hand that much and wants to see another card. Queen he obviously likes on the turn. I really feel AQ here.
