After she had spoken, Elenor picked up the pace and while she had a neutral expression on her face, she was exuding an air of self-satisfaction.
In her mind, she had done two things to the Prince fellow which had thrown him off his game; has had kissed and threatened him... Both of which he had been powerless against.
The kiss especially...
While she was doing exceptionally well (on account of experience and strength) with not letting how much the kiss had affected her show, she was quite giddy... The passion of that kiss... It had been incredible.
She saw in Hal, a potential sexual partner, and also saw the likely scenario where she had no choice but to kill him.
The formation all over the Devil Tribe-ruled segment was very important and it added security to the situation but she had a feeling that it would not stop things from unfolding as the Prince fellow wanted.
