The concern on his face doesn't escape his attention. No, it's familiar. It's what he's used to. That's the Lilim face he understands the best.

Kaworu looks him straight in the eyes, his face blank, the only intensity coming from the unnatural color of his eyes. "I intended to. I wanted to. And, I tried to."

"It is written on the palms of the Earth for the children of Adam and the children of Lilith to compete until one has perished. The fifteen of us born from Adam caused the Lilim to make enormous sacrifices and build incredible machines to fight us. Children, like you, were forced into them and suffered immensely from the battles. They're here, at Exsilium."
