Aurelia was startled to see Jessi appear, and even more startled at her reaction to Jessi's presence. Her body seemed to react out of instinct, and she looked defensively at Jessi who automatically had accused her of doing something wrong. Aurelia grimaced when Jessi then blamed the presence of a certain human on her. It was always going to be her fault wasn't it? This couldn't have possibly been Lestat's, who had caused a scene by yelling. No, of course not. He was perfect. She was the new vampire, the one who had ran away from her creator, betraying him, and she was the one that was going to be blamed when something went wrong.
The only thing that kept her from retaliating against Jessi was Lestat's presence. If he wouldn't have been there, she would have hurled herself at Jessi, and although she would have probably lost the fight, Aurelia would have left a decent mark. Aurelia didn't think that Jessi had a right to ridicule her. Not now. Not ever. And she was more than pleased that Jessi had came and went so quickly.
