I think he was just a bit more calm when he said the second line, he thought the Hulk was down for the count, and he was about to finish off the General. My question has always been why does he have this sudden disdain for Ross? It seemed like he respected the general while he was Blonsky, and because of Ross, he was able to reap the benefits of Banner's blood to be able to transform. I understand he's the Abomination at this point, but it's not like the Hulk, he's definitely in control of his thoughts and emotions. Then again, Ross did tell the soldier to shoot at him, so maybe thats it
