Well, Riku was certainly scared by that. An increase that constituted doubling in power certainly had sounded threatening. That being said, Sora kept it under control. He was sure he could throw Vegeta off his game. Meanwhile, though, it seemed like Riku had unleashed the power that he was charging right as Goku slammed his fist into the other's jaw. Likewise, Sora then smirked to himself. "Eat this, Prince!" He fired off several Ki blasts as well, careful not to hit Goku in the process. He had gotten much better about that. Riku took the opportunity to get in close and fight it out afterward.
