He was trapped on the roof, it was too far to jump to the next one so he just backed up to the edge. His heart was pounding away in his chest, Bruce knew he was getting awfully close, he didn't even have to check his watch to know that.
The guy in the iron suit had said something about them being Avengers, that sounded awfully ominous to Bruce's ears. What were they avenging? The Hulk??
Cap, he at least was able to stop and listen to, looking like a frightened rabbit every time there was another explosion. "Need me? I don't need anyone, I need to be alone and for everyone to stop chasing me! Now please just go and call off your soldiers! I don't want to hurt anyone!"
Then the lady came right out of the sky. Bruce had never seen anyone who could fly before and that pretty much stunned him into silence. At least until the helicopter took one from Thor's hammer. He ducked, his arms over his head, trying so hard to keep calm. "I need....need to be....far away from here..." he said to her, trembling as he tried to keep the monster inside of him.
