Liam had one specific Pokemon he was looking for. He had to find it on the way to Celedon, he just had to. While he waited for his Pokemon to heal he looked around the center. He could tell which people lived in town, since they all, like Joy were slightly paler then humans normally are and gloomy looking. He quietly asked Shiranui if he thought maybe this town's water supply had been laced with depressants. Liam also said that he had seen more lively people at a funeral, which sounds like a joke, but Liam's tone implies he is being serious.
