Someone who doesn't seem to have noticed his own desires... Logically, that means to Chase that it couldn't have been that strong, if Eiji doesn't know how personal it was. But there's something else, something that he can't seem to pin down in words. Medic...had achieved her Super Evolution with her feelings that, as far as he is aware, were selfless by nature.

"You cannot force yourself to desire something." Which is as far as he can get to determining why the 'just desire something' method isn't going to work. Roidmudes didn't achieve their Super Evolutions by simply wanting it, after all. And as far as Shinnosuke and the others had told him, Chase had been given human emotions at a cost; being human is simply not possible for him. He'd come to accept it. But he also had not been losing his senses.

"If you could have figured it out by thinking, you would have done so...is that correct?" In other words, Chase...would only barely be helping. Maybe he'd even be actively detrimental by saying things that show how little he understands of the situation. He knows well that words can wound, regardless of intent—and he's known a contradictory person or two.

"Does talking it through...help?"
