Hey, if you claim Ash is a Pedo I'll release my pearlshippy rage and throw you to the oit of doom, remember girls get their boost earlier than boys so he can't be a pedo.
Anyway, I theorize that ash should be round 13, remember the pikachu short of Movie 3? That was one year for sure, so kanto couldn't have been 1 year, probably 3/4 and OI 1/8 and JJ 1/8 as well. I'm not concluding that 3seasons=1 episode cause they have different speeds.
Altough this may be a little case of the Simpson syndrome during hoenn for some reason because Ash's maturity is approx to 13. Unless somebody is willing to caunt every day from the episodes, my theory stays.
