Bruce awoke. At first it took a moment for him to figure out he was in Stark tower. The bed was comfortable he thought to himself as he fell deeper in to the warmth. Then the thing that woke him up for the first time disturbed him again. Bruce opened his eyes and to his surprise Tony was lying next to him. They had started out on opposite sides of the enormous bed but now Tony curled next to him. Tony shifted again removing his hand from poking Bruce in the ribs.
Bruce sighed. He sat up and rubbed his head. How was he going to deal with this? Bruce had been aware of his rising feelings for Tony since they first met. "And I'm a huge fan of the way you lose control and turn into an enormous green rage monster." It was the voice that said those words that had haunted him in his dreams the next night. He wasn't sure what to think of Tony. Poking him and trying to provoke him in ways nobody who knew what he was would, ever would have done. But as they fell in to a pattern working side by side for the same cause Bruce began to forget that he had been dragged here to save humanity not to enjoy a mind as brilliant as his own.
Then he had had another 'incident'. He had come too in a pile of rubble. His first thoughts were of Tony. Was he okay? Was he alive? The next time they saw each other there wasn't much time for talk. Bruce had let the other guy out on purpose. His last thoughts before he woke again were. If you hurt Tony I will find a way to destroy us. Somehow they had all survived and Bruce was informed that the Hulk had been helpful. In fact he had saved Tony's life. Had the Hulk heard him?
Bruce sighed. Whatever had happened, the Hulk's response had been the deciding factor in him coming here. His love for science and the passion in which he was able to do it around Tony had been pulling him towards Stark Tower. But his ever present awareness that he could suddenly find himself killing the very people he loved made the argument for leaving. The fact that he might have feelings deeper than friendship for Tony had been a neutral factor. He refused to let it decide things. That's how Bruce was, calculating. It was numbers and figures that made sense to him.
Bruce turned to Tony and fell back in to bed. He wandered how long it would take to find another place to sleep; he hoped it would take a long time. Bruce turned to face the man next to him. He fell asleep in the soft glow of the Arc reactor.
