Zane didn't feel that whatever issue his father had to deal with could be held against him. Why should he care if people complained to Bernard about how he handled things? Changes needed to be made now or later. Some getting upset about him doing it only reinforced his belief that putting it off would only make matters worse later.
"As much as I need you to help me with what we've just been talking about, I think that that conversation will have to wait till another time." Zane turned away despite the other man cussing and hissing at him, still unable to do much with the handcuffs on. They wouldn't be coming off any time soon without him having the key. Zane didn't intend to give it to the other man either. At least not until he learned his place. It would do no good if the other scurried off before he thoroughly learned the lesson he needed to be taught. That would lead to Zane wasting time at another point which he sorely didn't want to do.
