He doesn't push on the thanks and just eats while he considers the answer to Frank's question. "Yes. I shouldn't be able to do what I do and people have an expectation of what it means to be blind. I can try to pass myself off as sighted, and it works in brief bits and pieces, but I can't make meaningful eye contact or do a lot of other things that you can do. So it's just easier to let people think I'm not as capable as I am than to have to explain chemicals in my eyes, super senses, training with a ninja, yadda yadda." He stirs the food around in the bowl. "People get weird about it once they know what I can smell or hear or taste. Some get self conscious. Some get worried." Frank doesn't seem to be capable of either of those things so it's easier to talk to him about it, and he figures after all this time, he owes some explanation.
