Well, Vegeta would have certainly been embarrassed at this point. The fact that a Prince of All Saiyans, as he loved to call himself, was exposed to such an odor was an embarrassment for sure. Sora was still mocking him of course. Riku was doing his best to fool around with him in his armpit. That was when Sora got an idea. He figured that he should go look back at Son Goku. Having not known what happened to the other Saiyan, he thought it was apropos to see what Goku thought of what was going on. At this rate they might not have even had to kill Vegeta. That was when Sora thought of Napa and wondered if it was even safe to keep him around or not. Really he wasn't sure at this point.
