When Leo had been popped the question from Erin, it had come as quite a surprise for himself. It was the first time that anyone had ever asked to learn his ability before. This ability he had devoted himself to, no one had taught him it, so he was considered a new original.
However, unlike other abilities and powers, his was not one people could just see with the naked eye. There were no flashy explosions and such, and even if he did allow for anyone to learn it, not many would choose to. For the simple reason, if the ability was on it's own it would be able to do no damage whatsoever.
It would have been classified as a supportive type ability like super hearing, sonar and so on.
"Do you really think it's the right choice?" Leo asked. "After all, unlike me you are not blind, you can rely on your own eyesight."
