Paul knows the look on Midoriya's face from the first times the Bene Gesserit conditioning began to connect with him. It's the pivotal instant of synthesis, the threshold of choice to reach beyond one's self-understood limits. It looks like Midoriya is about to do something that puts Paul on his back, and that's a differently inflected thought in this context.

There's more to doing dishes than he thought there would be, but he's come to find a meditative calm in it. This is only slightly disturbed by Kaworu falling against his back. He twists to look at him, and so ends up following his gesture to Midoriya anyway.

"You don't actually have to listen to him," Paul says over the running tap, bordering on apologetic, "Or me."
