Nah, just the actual episode. I've got no idea what the context is of half of the things in your post, but I do know that Charizard has nothing to do with this episode and that Ash already realised at the beginning of the episode that Poni's Nurse Joy wasn't the same Nurse Joy as the one from either Akala or Melemele.You rather we discuss daikon radishes or something.
I'll just throw in something else. I liked the bit of continuity with the main character's pokémon liking or disliking the radishes. The ones that liked it early on in the episode when they first tried it were the same ones who were also eating them at the end of the episode when everyone was having dinner, while the pokémon that didn't all ate berries instead.
