Bruce Banner stared at the cube that had given him and the rest of the "Avengers", so much trouble turning it around in his hands as he studied it curiously. He couldn't help but want to understand the thing a bit more. What could it do? What were its limits? The tesseract {I think that's how its spelt} was pretty in its way.
"Keep toying with it and you could get hurt." Natasha said offhandedly watching as one of the scientists studied the tesseract. He at least was a whole lot more mature than the other wealthy scientist that she knew. But Tony Stark knew that she meant business and actually respected her in his own way, as well as Bruce who the other man saw as a friend as they were the most scientific intelligent of the group of adults saving the world from Gods and whatnot.
