"I knew it!" Rowan exclaimed. "I knew that human bastard was one of them!"
Hearing such language from Rowan's mouth irked Adrian. Before his death, Rowan had always treated him kindly. But it seemed all of it was a facade to take advantage of his [Analysis] skill.
Now that Adrian realised it, Shu and Vincent were similar to their brother in that aspect. While Vincent was a poor imitator, he still acted kindly to the strangers, only revealing his true side to his guildmates. But the team was aware of his two-faced nature.
As for Shu, he was all buddy-buddy with Adrian when they were attacking the Tulkas but changed tone immediately after he saved Vincent from Adrian's rightful wrath.
Now that he thought about it, he wondered if Amelia was also like them. Adrian didn't want to feel like she would betray him, but what Bellion said about the contractor being someone close to him had messed up his mind.
