Nicholas hadn't entirely known how to react when Ceridwen admitted to being a witch. Before he had been enlightened about the supernatural and immortal part of life, if someone had told him they were a witch, he would have nodded good-naturedly and sent them on their way. It was different now, and Nicholas knew she was a goddess but it still sounded ridiculous and he had to school his features into a stoic expression so as not to look like he was simply humouring her. Of course then she mentioned what the liquid was for, and all sense of stoic aloofness faded away.
"You are a fucking godsend," he breathed, before shaking his head. "Sorry. I didn't mean to- Can I tell you something? I haven't told JJ or Jesse but I think you might be just the person to understand." After all, Ceridwen was ancient, surely if she would have seen worse than what he was currently going through.
