Hulk didn't spend a lot of his time worrying about deductive reasoning. In fact it was fairly well known that he didn't even know what deductive reasoning was most of the time. It depended on the day, the situation, and the surroundings, whether or not the green tank was going to go to the trouble of figuring things out for himself. Which made the moments in which he made the effort that much more important.
He watched while Superman dropped the boulder on the dragon and his brows knit tightly together, his head turned abruptly from one side to the other before his eyes settled on Superman. He was about to swat at him again but he fought every instinct that told him to and remembered the boulder (even though it had only been a handful of seconds it was similar to recalling a memory from earlier in the day).
He was flying but he wasn't Iron Man. He was strong but he wasn't Cap. He was nice but he wasn't Spidey. He didn't know who he was but he knew he wasn't an enemy. Hulk understood words, he understood sentences, he did, in fact, speak English. Just not well, and not all the time. What was the point? He understood what was being asked of him and while he knew he could get back to town on his own there was no saying what might be waiting for them or what he might do trying to get there. It was well established that Hulk was mostly incapable of walking down the street without causing damage, and if he traveled his way, he'd leave a path of destruction from the highway to the strip.
He felt Bruce pushing against his mind, and he ignored him, as he usually did when things were dangerous. He knew better how to keep Bruce alive than he did but Vegas was not big enough for Hulk. He couldn't stay in the desert, Cap and Iron Man were out there somewhere and so was Spider-Man. He didn't know how to respond. Confusion on Hulk's part just managed to piss him off. And he grunted clearly annoyed, huffing and wishing for something to throw. He narrowed his eyes and looked at Superman almost suspiciously. And then looked around at his surroundings. He knew what he wanted to say, wanted to suggest...He pointed back toward the strip where there seemed to be more and more chaos happening. He knew there was more going on, be it Loki or something else that needed stopping. "Bring here. Hulk smash." It wasn't so much a question as it was a suggestion.
