Midoriya says everything that should be said, so Paul at first only follows it with a nod as he slides his hand to the side of Kaworu's face to lightly stroke from the outer edge of that eyeliner towards his temple. (An impulse to bend - to cast a shadow over - slips through him like quicksilver, but he lets it flit away.)

"We'll all protect each other," he agrees, and lifts his hand so he may reach over to clasp Midoriya's shoulder, this time obeying his impulse to close the circle between them. "And look out for ourselves, or we'll answer to each other."

He knows that's an unrealistic expectation, given what this place is, and who they all are, but he can believe it while they're here like this. He can believe they'll try, which counts for something, as they're teaching him.

"No smudged eyeliner." That one, on the other hand, he knows perfectly well won't happen - although, when he thinks about it, who's to say what angels are capable of with cosmetics?
