All through their journey to Arianna's dorm, she wasn't comfortable with Naomi coming with her. Her mind was weighing too many thoughts and what if's, she didn't know Naomi as she would brag about knowing the girls even though they have known each other for some months now. But something about being around them, was familiar, something comforting and bonding for her.
She wouldn't say the same thing with Naomi, for her, she feels her hair was always standing. Mind at alerts from any attacks from her, and she does not have any peace of mind around her. Arianna and Naomi got to the formal's dorm, and while she was apprehensive, the latter was in a good mood.
She had so much she wanted to do to Arianna, or she would rather put it in a formal way, so much more she would like to do with Arianna.
