He's more than nervous isn't he? Yukiko could sense it and had an idea to try to keep him calm, hopefully it would work. With one hand locked with his, her other which was still on his shoulder, pushed him over gently so his head would try and rest on her. As an added bonus, she started letting her fingers go through his hair again, a habit to try and either keep him calm or just a gentle reminder.

"It's alright. We're good up here."
