Alvin hadn't bothered to check about Casper and Gianna other than knowing Casper will have to go to the Coastal city. So Alvin had no idea they were in the hotel.
Alvin chose the hotel because it had a good restaurant and was near to Johnson's communication center where Anya was at.
He didn't mind the unexpected coincidence either as he anyway wanted the couple to know he was with Anya. They wouldn't dare to pull random stunts on her. However, Zane hadn't planned to include Zane in his plan.
He asked back without responding to her question, "Afraid of them?" His voice lowered in concern.
The fear of 'being with him would endanger him' was too strong in her. It was very important for her to trust him and herself to get rid of the fear.
