Sora's lack of stealth made him a pretty easy target, whether he was aware of it or not. Roxas was also prowling among the exercise equipment. And it really wasn't hard to spot Sora. Exercise equipment didn't exactly provide the best cover.

Roxas smirked as he took aim from behind an exercise bike. He planned to retreat to somewhere with better cover as soon as Sora noticed him, but in the meantime, he got off as many shots as he could before then.
