[After several steps, Zero can't stop himself from looking back over his shoulder at her. The familiarity of her scent always a soothing balm for his otherwise frayed emotions. Yet she was normally the one causing all the emotional upheaval in his life as well. Absorbing the sight of her, he didn't really pay attention to where he was moving, just continued to take a few more steps before turning back in the direction he headed.
He hadn't expected to hit a hard wall in his movements, hadn't even thought about something like that being a problem because there had been so much room in front of him when he'd turned to look. The impact was such that it knocked him off balance for a moment, looking over his shoulder to see if she'd witnessed his smooth move into nothing. It wasn't until he overheard the words she said that his attention turned back to the invisible wall he'd run into.]
Not good.
[The words were mumbled softly but still said out loud.]
