Teeechnically Dragon did see Luffy at Loguetown when preventing Smoker from arresting him, though since that wasn't a face-to-face encounter and they didn't directly interact, I guess it doesn't really count. I'm still laughing too hard at the bottom right panel on the last page. Also at Robin's reaction to the dragon.
