First off, in the scene when he destroys the giant robots, all might literally told him to take out the one worth now points... so that was the plan anyways. He would have ed even if she wasn't there. She just happened to be there. And when she pleaded to share her points they didn't even do it cause he ed anyways. And do you really think if he didn't get into UA no one would train him. He obviously would still be a hero even if he didn't get into UA.
