In her surprise, Elsa spoke before thinking, a soft sound of surprise leaving her. "A spell? I didn't..." Catching herself she lowered her eyes to the ground, frustrated with herself. She had no idea when she was doing magic and not, at times the exhaustion she felt afterwards being the only hint. Maybe if she had examined her thoughts and actions just now, she would have realised what she was doing. Or maybe not. She must have had training at some point, but it was not something she could remember. Sighing softly, Elsa could but agree with Imenry; she did need someone to train her in magic, to make her aware of the correct methods to harness whatever power hid inside her. At this very moment, she could not stop a slight surge of smug satisfaction. She might not be a warrior, strikingly blue painted as Imenry, but she was not utterly useless.
The tactic seemed to have worked too which was also gratifying. Studying Imenry, Elsa debated telling the truth. Any spell had not been on purpose and the other woman thinking so might rattle their tense relationship needlessly much. At the same time admitting that she had no control over the gift that was perceived as her one advantage to the wardens rankled. In the end Elsa stayed quiet on the subject, only smiling sweetly at the warrior woman. "I am sorry," she said, voice wavering on a hairsbreadth between insincerity and true feeling. "It was not my intent." That was true, but ought well to be understood as if she had just gotten a little too engaged in their training. Fisting a bunch of skirt fabric in each hand, the mage waited for the warrior to recover.
