"Yes, that looks right." The problem was that when Sayoko had taught her before, she'd explained the folds but hadn't used the names that this book used for them. Nunnally could sometimes tell from the diagrams how to match the words with the movements she remembered, but other times it was more difficult. This was one of the former -- the folded square was familiar, the base of the crane pattern she knew as well. "Now you... lift this, here, and press it down?"

The gesture he'd made while thinking was a little peculiar, almost like he'd been typing... a mnemonic of some kind? Interesting. But whether he knew much about origami or not, at least he was willing and able to help her, which was nice of him. Or perhaps he wanted to know more about her simply because of her brother? It had happened before, and he was certainly setting himself up in a position of prominence here.

Nunnally only smiled, though, taking a fresh sheet of paper of her own and imitating the folds he was making without giving any indication of her own thoughts. "He seems to be so busy here, working on so many projects. I hope I'm not distracting him too much of his work... but I suppose it's in the nature of a brother to worry about his younger sister, isn't it?"
