Sayaka who just killed a person who looked like Oliver, felt a bit irritated. Even though she knew that this James Bourne was different from the Oliver that she loves, it still felt weird killing someone that looked like him.
"That's pretty impressive killing the wolf of the battlefield, even though he was a weaker version of the original he was still pretty good. Yet as expected a failure can never amount to anything but become trash."
When Sayaka heard what Richter said it made her a bit angry. She now kinda understood why the cloned James was acting like that in the end. This old man treated him like trash after creating him. It was obvious that he was always compared to the original and never treated as his own individual person. Even though she didn't really like the clone, she somehow still felt a bit sorry for him.
