It seemed that she hadn't missed anything. However, when he went on to describe what his intentions were for the morning, she kind of wished she had. A feeling of her heart plummeting in her chest consumed her, but she was quick to follow him- offering a verbal agreement as they went. "Yes, sir." Adelina answered, trying not to allow her nervousness to taint her tone of voice. She took special note of the direction they traveled off the Col, as she suspected there wouldn't always be someone to guide her to the training area. Adelina glanced around the space, panning over the different things that lined the walls. But Sirius was quick to get things started, so her attention landed on him as he spoke.
How he asked her to stand went against a lot of what had become muscle memory for her over the years. She naturally carried a lot of tension in her shoulders as a self-coping mechanism. But by spreading out her paws to make a larger base- the stance forced her to square up her frame, and she hated it. She gave it her best shot, though. And while perhaps it wasn't quite where she was supposed to be with her footing, it was a lot different compared to her usual 'mousey' posture.
Adelina felt like a fish out of water. She glanced back and forth a couple of times between Sirius' paws and her own. She flexed her toes in her back paws, and front left paw, but that was the best she could muster. With clear question to her expression, she sought out Sirius' face for a moment before looking away. "This doesn't feel right." Even if the stance was correct, she wasn't sure it would feel right. But that was beside the point.
