Think of it this way: how efficient would it be if they were unable to accomplish anything while Shinji was on his penguin-feeding trip because they were too stressed out about waiting for him to come back? It was a real possibility! At least for Kyoko!

Meeting Shinji's eyes for a moment, Kyoko gave him a bashful "thank you" before meekly setting out, her hand tucked safely in Kaito's. Let's all turn around then and trudge back to the inn. Please don't be too surprised to see them again so soon, nice receptionist.
