Aww man, don't even joke about that. You might jinx it and it'll actually come true.decisive match! Dawn vs Nando!!
Its not like it needs an arc for it, I think if they were going to do a Pokethlon arc, it would have been when Kazu and Kotone were around.I'm surprised the Pokethlon is only one episode.
They can't cover all the events in just one ep. Maybe there will be more future Pokethlon eps.
