Ever observant, Midoriya can likely pick up from the easy, reflexive looping of Paul's arm over Kaworu's bundled, nestling self that this isn't a new configuration for them. Paul doesn't regret it, but he does think of it only after it's already done.

Then Midoriya calls attention to the bright plastic packet in his hand, Kaworu makes his offer, and it's all a little bit much for the condition he's in. Paul's already creased eyes narrow further, and he briefly releases Kaworu in reaching for his weapon.

"I know how to use your primitive Earthling protectives," he says, archly, and hurls a pillow at Midoriya with all the speed and accuracy he can muster. It's an excellent throw, under the circumstances.

He's not flustered by any of it. There's nothing about things like that which Paul doesn't understand the mechanics of, or sees anything to get worked up over about. He's simply insulted by the implication of his ignorance.
