Adelina was definitely far more friendly than she had been before - genuine friendliness over the forced version that was required because of Leone's status as a Princess - while Nirinia didn't seem to have changed at all, though the change that had happened was definitely one we weren't going to see anyways.
I imagine the Djinn-Orc's demands for physical intimacy were now being met if they had become engaged since the last time we had seen them, something that was non negotiable for Nirinia since she seemed to be treading the same path that we were.
In other words she was a degenerate who required that physical closeness a majority of the time, and honestly I couldn't blame her considering the type of life that she was living; the constant danger and immense pressure placed on her shoulders was one that required some kind of outlet, and the most common just so happened to be the world's oldest vice.
