Huh. Well, Goku learned something new there. "Huh," that was his vocal reaction, as well as his expression. His brows furrowed as his eyes widened in surprise. "I wonder if he knows how to use qi, too. If I see him, I'll have to ask him."
Goku stretched a little, then shook his head. "Nope, no wires. Energy though, yes." He didn't mind questions. In fact, if people asked him a question, Goku would answer as honestly and as fairly as he could.
