Friedell asked, "Harold, tell us quickly what was going on with this matter."
Harold knew that what he did was shameful.
If he had been frank, he didn't know whether Owen would help him, but Friedell would not have stood by him.
So, he naturally chose to lie, thinking that he made a smart decision.
Harold embellished the story by switching the roles between him and Greg and reversing the truth of the matter.
In other words, in the version heard by Friedell and Owen, Isabel became Harold's girlfriend, and it was Greg who wanted to take Isabel forcibly. And then, Harold helped and was finally beaten into what he was now.
Neither Friedell nor Owen had any doubts.
Hearing what Harold told them, the two of them were furious.
From their perspectives, Greg had already become a crazy person under the protection of Luther.
However, neither Friedell nor Owen had thought that it was Harold who was insane.
