Cynthia was extremely tensed since she thought that Ed was clueless about what kind of person Zina was really, but it wasn't true.
He wasn't fully aware but was wary toward Zina.
The wish to capture the main figures behind the illegal genes experiment led him to do a risky thing.
He asked Zina to participate in his experiment so, that he can keep a close eye on her while acting all naïve and being off guard in front of her.
But at the same time, he made sure that every important research was kept hidden from Zina.
"What about you? You asked her to help you in finding cures for the children, who are miserably dying because of those illegal experiment. What if she figures out that you are also one of that case?" Wayne crossed his arm and legs.
What he was saying was not wrong but even though Ed didn't reply him, he knew what his friend was trying to do. He was risking his own life to found out the one who was behind these experiments.
