What they say is that it will easier to enter in almost any Episode without need to see the previous. This will make most episodes to be self-contained (although they said there would still be two-part episodes).BTW Looks like the less plot thing someone said in the begining are starting to not be true at all
-We have a Two Parter ending in a cliffhanger (Galar Episodes)
-A recurring Pokémon (Gengar)
Not that im complaining, I kinda like this
However, they've never say there wouldn't be a continuity between Episodes.
Gengar appearing again wouldn't be so different from the Pokemon of Go appearing again after they are caught.
