It really isn't that difficult; even Lian, whose grades don't exactly count as outstanding, can handle it with ease. As long as she's serious, she won't make any mistakes.
Starting a few minutes ago, the instructions Teresa has been giving have gotten shorter and shorter, and Lian's job is to turn those terse lines into commands that the Battle Six type can understand, then do some harmless fine-tuning within the prescribed limits.
In theory this shouldn't put any strain on her at all. After all, as someone who's constantly around Foster Ward (if you misread that, go face the wall), Lian herself might not have much in the way of military attainments, but she's a very capable secretary. Whether it's her work as secretary in the student council, or the daily chores in the Law Enforcement Force, she's always been able to carry out Foster's orders perfectly.
