Iris didn't want to talk with her alone not because she was afraid, Nala would do something horrible to her, since she used to have this kind of attention whenever she was close to her, but because Iris didn't think there was something for them to talk about.
She knew, Nala was not in a good situation, since she lost her father during the attack and now she was so far away from her home, from the people she knew and was surrounded by the pack member, who didn't care much about her.
The king had gone and no matter how horrible it sounded, but without the king, she was nothing. The respect she got due to the fact she was some sort of the king favored woman, though she couldn't be called as his mistress.
