I just continue to be annoyed by Isabelle's role. Whatever her role even is, I don't know. Frey doesn't train her. He might have given her some random tasks pretty much anyone could have done, but that's it, and it's only because she happened to conveniently be there. She has "stolen" a couple of morsels from his training, without Frey really promoting it. This makes her a one-sided follower Frey tolerates, but that's all. It's not a proper role for a significant character, but it's all she has got. That's precisely what annoys me. If she had any pride, she would hit the road and use what she has learned so far to find her own destiny because Frey, for sure, isn't going to provide her with one. In fact I reckon he treats her like he does just for that reason: to make her go away and get strong on her own - or die trying. But she doesn't get the clue, which makes her so sad as a character.
