Katerina and her bodyguards waited for Mr. Nelle to finish his call with Ian. She didn't want him to think that she had overheard his discussion with him.
Unfortunately for Katerina, when she began to move, Mr. Nelle had already started another call, and it was one that she was glad to have overheard.
"Are they cooperating?" Mr. Nelle asked in a calm and confident tone. It was quite different from how he spoke with both Eric and Ian.
"Good, good, make sure their relatives are continuously watched." He ordered, making Katerina realize that he was speaking about the employees from the Reyes Group that they were blackmailing.
