While the girl was talking to Maxwell, Hwang looked around to find a way to get rid of the ice cream, and found a young girl sitting alone, looking quite bored.
As he walks over to her and hands her the ice cream, he has no idea that he was being watched closely from afar; from a tall building in the city where a cloaked figure spots him walking from the safety of a tree in the plaza into the open. It watches closely, quite confident that the trainer will not detect him from the same distance, but trying to retain his focus towards the rest of the group who are hidden behind the tree...
When Hwang returned to the group, he hears Maxwell's suggestion to going to the mainland. "Wait a moment," he said abruptly. "You mean this Ash Ketchum returned to the mainland? He could be anywhere in the world right now."
Solar turned to him, his thoughts transferring into his trainer. "Some of us here are psychic, remember? All we have to do is head in the right direction."
"That doesn't convince me..." Hwang thought back sarcasticly."
