Truth behind the brothers' powers

The people in the room burst into a fit of laughter following Alex's words. This person sure had the ability to lighten up the atmosphere with his antiques.

"Stop laughing." Alex mopped as he turned to face Happy, "What did you mean by me, and brother Zed should also let ourselves loose. And how are we stronger than others? You know something don't you?" He tried to change the subject.

"Literal meaning. And yes, I know everything about it. After all, I am responsible for it." Happy turned serious.

"Don't talk in riddles Happy. Come to the point." Zed was getting impatient.
