Interesting, it says (and this was kinda hard but I did this on my own) that during the Kanto Fair, a charmander hurts itself during a performance. While waiting for charmander to recover, (and this is where it got tricky) Satoshi and his friends recall the time where his charizard was a charmander. They began to speak to N (who's in latah)
Gah, nothing new.
EDIT: The description mentions lata (latah in english) Latah is a cultural specific reaction to stress (southeast Asia to be exact) where the person engages in repetitive speech or they daze and hyperventilate. I think the reason the scan mentioned it was because this charmander and N pretty much engage in conversation while the Pokemon is in latah. Which makes sense because N can sync and talk to Pokemon.
Just a thought.
