Kai didn't plan to show up in this place. He was sent by Zeke to make sure that Kelly and Chris didn't create any trouble before they went back home. He was also warned by Zeke to make sure that Kelly did not do anything outrageous for her own sake. That was why Kai was there. At the same bar. Watching them.
He had been following them for a while now until they ended up in a bar. Kai was too engrossed at listening to her rants that he subconsciously turned to look at her because he became worried that the girl would actually go and try to beat someone up. He knew that Kelly was a strong girl and definitely a well-trained fighter but she was still only a human and she wouldn't be able to beat just any random man in this place, except for the human guy who was with her. And that was why it was too late for him to hide when she suddenly turned towards his direction.
