There was another long pause as Tony tried to digest this, figure the reasoning and put all of the parts together, but the facts he had were confused, subjective, and didn't add up. "You're not even old enough to vote," he settled on at long last, looking really quite desperate to understand. He could concede, under duress, that training young heroes had its merits. Hell, a training process for those with enhanced and extraordinary abilities no matter their age was a welcome idea; Xavier had been doing it effectively for years with mutants, as shoddy as his recent record seemed to be. If there was no way of convincing people out of the capes and masks business, equipping them properly would make everyone just that much safer. Somewhat incongruous with the whole idea of the super hero, but this was Tony trying to understand. Unfortunately, he couldn't claw through the wall that clearly stated, to him at least, that institutionalizing the concept also encouraged it; in minors, and in those otherwise completely incapable of handling the pressures.
So, no, Tony just didn't understand. The clearest question he could prepare for Cassie, though, was "Why didn't your friends want the training?" He had his suspicions, but he hoped her answer would provide a little more clarity for the whole process.
