At first, he didn't know what she meant by follow him, as if he was taking her somewhere she didn't want to go, and then he realised what she meant. "Oh! Okay, I'll wait for you to write," he nodded, although admittedly there was going to be a pressure on him to write her the sort of letter she would expect from him. Maybe they both just needed to relax.
"Oh, yeah, I never get carried away like that," he flashed her a smile, moving through the crowd quite easily, as if he just walked right back in to his rightful place among this crowd.
