interesting... I don't know if the dub mentions this, but in the Japanese version, Satoshi mentions how Bayleaf shouldn't use Tackle on him. At the very end of the episode, rather than tackling, Bayleaf slowly walks up and leans on top of Satoshi, after which Takeshi proclaims that it learned Body Slam (which is called "Noshikakari", translates to "Lean On", in the Japanese version). So aside from Bayleaf's post-evolution characterization, it seems as though this episode's further important for being the first occurance of one of Bayleaf's most proficient moves.
