He'll definitely need help understanding legalese when it comes time to buy anything and, considering how many civil projects he interacts with in his normal life, I wouldn't be surprised if he ends up asking a lot of questions about otherwise boring as hell stuff in the process of trying to recreate a slice of home within the Pokémon World. Gotta have the nest ready in the off chance his missus drops in though right? XD

Once he's on the road proper and actually interacting with the world it should be easy enough to arrange a meeting between the lads. Does Geddoe interact with gyms or pursue the typical trainer journey at all?
