To train a hound

Written for the SanSan Russian Roulette on LJ. Here's the prompt: 'Pre-relationship, post-canon. Sansa is acting Lady of Winterfell, Sandor is the master-at-arms. Sandor catches the words of a conversation Sansa has, defending his gruff behaviour to that person. Afterwards, he confronts her privately with it, mocking her, but also secretly pleased.' For Winterwasp.
