In my army, she would have been transferred. Relationships between command and the ranks often end badly. This is not my command, however. Have a care you don't come down too hard on her to compensate for perceived favoritism.
I have a good group. The only ones who aren't naturally level-headed are experienced enough to act sensibly. I have been working toward having everyone trained on at least one ranged and one close combat weapon, and Logan and Bruce have been working with everyone on unarmed combat. Skills are improving nicely, and all are growing used to working together.
