"What do I owe this pleasure, Klaus?"
Klaus assessed the sharpness and hostility in Silvia's eyes. For the past two months, Klaus had always kept an eye on Cassara and Silvia. These two always had this love and hate relationship, until years later, hate would be the only thing that would remain.
During this time, before the regression, Silvia and Yulis also had a good relationship. Hence, there was nothing wrong with Silvia's tea time with Yulis since she hadn't done anything suspicious. Moreover, Silvia had acted the same: hostile, always wary, alert, and sophisticated.
It was hard for Klaus to find out whether or not Silvia and Yulis had regained their memories since both of them had drunk Lilou's blood and it wasn't just a small amount. Lilou enhanced their blood, after all. He couldn't also ask them outright, knowing giving them the idea of the regression would do them no good.
