I was rewatching the pokemon original anime and i
noticed something at episode 13 the episode when the
giant dragonite appread.
Ash was lost and went to the lighthouse ho bill and at the
door there were many scriptures of pokemon and among
them there was a mew two scripture.
According to the original pokemon timeline mew two
wasn't discovered and there were only 150 pokemon and
at the exact episode bill also said the same thing but at
his door there was the 151th pokemon.
