Answer:Go to Route 120 and go south. Cross the bridge, and you'll see Steven. After a battle with his Kecleon, he'll give you the Devon Scope. It alows you to see any unseeable Pokemon. Now go back to the gym in Fortree City, and press "A" to the place where you can't get in. The Devon Scope is automatically used, and you'll see a Kecleon getting away.
