Recording has been done in his family for many generations, and it comes with a whole apparatus of rules: when to record, which fields to record, which matters may only be written on particular paper. He memorized those rules as a child, more thoroughly than he ever memorized the mantra-wheel.
Switching languages costs him nothing, accent included. He is precise about which language carries which kind of speech—one for asking directions, another for asking about a person.
He is cheerful and quick to laugh, the first of the new students to be on speaking terms with people from every branch. In his family tradition that counts as a skill too: to record someone, you must first get them willing to stand in front of you.
He carries a notebook trimmed narrow, exactly the width to slide into an inside jacket pocket. He does not hide it while writing, and if someone leans over to look, he does not cover it either.
