Namine was sure Sora was a good teacher when it came to swimming; he'd grown up knowing how to, after all. Though it seemed that if they weren't careful, Riku might end up mostly teaching her. Taking the offered hand, she smiled. "I know. Thank you."

She kept hold of the hand as she began to make her way towards the others. It looked like Xion was following Sora over to the wall, so she needed to hurry to catch up. Her grip was fairly loose, though, giving Riku a choice as to whether or not to keep hold of her hand and follow, or keep an eye on things from a distance.
