You recently met Lo and you were the one who followed him like a faithful puppy when you were at university. He mistook you for an automaton, who, as he decided, had a purpose to keep an eye on him. When you suggested going for a walk together, he decided that you were probably sniffing out something about him in order to pass the information to someone who was really worried that he was finding out something about the island and the automatons: "No... I wanted to go out with my friend today, I'm sorry."
