What will you do about Imogen's trepidation?

Ignore it; either she'll cope or she won't

Imogen doesn't relax throughout the whole meeting, her nerves stretched taut the whole time. However, she still manages to keep her wits about her and carry on an intelligent conversation, discussing her thesis with candour and insight. You watch her like a hawk, ready to jump on any transgression or distraction, in order to deliver a most exemplary chastisement, but it turns out there's no need.

Your student doesn't even breathe a sigh of relief when you dismiss her and she politely takes her leave. From your window, you watch her crossing the quad (a very pleasant view, it has to be said), the tension in her bearing not beginning to subside until she passes through the arch into the next courtyard. Imogen's next turn to act as your maid promises to be quite exciting, if she's still as frightened of you then as she was just now.
