Why is it hard to figure out who’s in the Pokemon Trainer Club?

By the time we’ve been through the whole show, we’ve learned a few things.

1) The Pokemon Trainer Clubs are not real.

2) The “clubs” are actually really much more like an amusement park than a real club.

3) The real clubs are actually full of children.

4) They’re not real because they’re part of a fictional movie.
