Celeste felt like she could breathe a little better once the other left. She didn't know what to do though. She covered her face with her hands as she tried to let everything sink and figure out what her best option was.
Did she think that Bane, Divo or whoever was going to hurt? If she based it off of the way that he had interacted around her, her first response would've been no. That didn't mean though that things would stay that way if she ended up upsetting him or saying the wrong thing and that was what concerned her.
The only thing that she could accept for likely being the truth was the fact that he wasn't fully human. She had never seen him transform or anything of the sort however which created a touch of doubt at the back of her mind.
The whole mate thing and becoming whatever he was.. that was taking things too far for her. She hadn't even rightly sorted her feelings out about him yet and he was trying to impose his own expectations on the situation onto.
