As Ryan stepped onto Route 213 he could instantly hear and smell the ocean, despite the fact from where he stood a forest stood between him and it, was just a short walk around the corner though to get to the ocean, even he could tell that. Stepping into the tall grass which separated the grassy western portion of Route 213 with the sandy majority the Water Channeler would hear the unmistakable sound of a Poliwhirl, no doubt battling some other sort of Pokemon, perhaps some bird Pokemon.
A short walk forward to investigate Ryan would find a Fisherman who had evidently just knocked out a local Chatot with his Poliwhirl. It was strange to see such a trainer battling on land and not fishing up his opponents but not exactly unheard of. The Water Channeler would also note on the Fisherman's cap a patch in the style of the Fen Badge sewn to it, the Fisherman a gym trainer no doubt, likely here to train as ordered.
When Ryan finds the Fisherman by following the sounds of battle and then spotted the Fen Badge Patch, he knew he had struck paydirt. But just wandering over wasn't going to do him any good and there was plenty of room for the pair to train.
And this is just what Ryan would do, rooting around to find a wild pokemon to fight!
