[...well Katsa you asked.] There's this condition called heterochromia that's basically a discoloration caused by either having a lot of or too little of a certain kind of pigment that matches...which is also different than albinism since that's when something's lacking pigment in general. With heterochromia what happens is that one of your eyes irises is pretty much not receiving enough melanin or it might be receiving too much. Usually I've heard of it being due to genetic make-up but it can also be caused by disease or an injury or even chimerism if you're mixing body parts due to transplants or cell mixing.

[Science.] But like I said, I don't think hetereochromia gives people in my world super-skills.

[There's a shrug in response to that last question. It's okay, Katsa, Hiro asks too many questions, too.] I mean it was my idea. I had something to take care of at home and so I did it with their help. I guess I'm kind of the mastermind behind everything and the leader of our team. I designed the suits, I figured out the plans, and I stopped the guy we were going after but they helped a lot. Not sure how much it matters here though when the rest of my team's at home.
