Obviously, a good little soldier would say I'd love to throw myself back into military structure, thanks! You know me! but that isn't actually her. She refuses to allow it to become her. It would also be deeply rude to call the Doctor all the way here only to change her mind. So, even with Nobunaga's chosen phrasing making it clear to her what would endear her to him further...

She nods at him, stops, and then bows instead, eyes fixed onto the ground.]

Understood. For now, I... would like to go with this. [She rises, and her eyes slide towards the Doctor.] If it's possible. Like Klaus said, I have no intention of being a burden.
