Yuuko has made him cautious, taught him that there are some spirits that even he cannot see. There are those that attack indiscriminately, but those are the ones that he finds himself the least fearful of. They are impartial, attacking anyone that fulfills the conditions that they wish. Their brutality makes sense to him, even if he doesn't like it.
Doumeki blinds them both to the things that happen around them. His ability is both a blessing and a curse to Watanuki. If he is around Shizuka, the nausea and disgust disappears. If he is around Shizuka, he isn't able to see the things that would bring them harm, is not able to protect the both of them, never able to see the things that cause the animosity between the two of them, the ones that cause the problems that maybe he used to want, but maybe not not any more. But it never seemed all that important to Shizuka, even if Watanuki thought it should have been. Perhaps, somehow, Doumeki knew that one day he would be able to see too.

Piercing blue, like sapphires. If Shizuka were the type to write poetry, he could have picked any overused cliché to describe Watanuki's eyes, every sappy word that didn't ever come out of his mouth. But they were different, after the exchange. To everyone else they were the same eyes, the same deep blue. But when Watanuki got angry, scared, sad... his right eye would turn gold – gold like Doumeki's – and Doumeki would see. And Doumeki would come, come to save him, to hold him, to comfort him. And he would wonder how he had been able to stand being blind for so many years.
