Lover of underrated characters
I'm expecting a slow pan to Oak's lab that may show one or two of Ash's Pokemon before cutting to Ash's Pikachu as a "LOL NOPE" kind of attitude just as a prank on older fans. I don't know if they would actually go so far as to do that. But who knows if they might feel annoyed by all the older fans wanting to see Ash's Pokemon at Oak's lab.
That annoyance could easily be resolved with a simple proper lab episode where we actually see everyone
A major part of the whole factor is they just dumped the Kalos squad there, didn't show Ash introducing them like usual and they were completely absent from SM. I'm no fan of XY but Ash's team was one of the few enjoyable parts and it felt extremely disrespectful to just ignore them like that. I'd like to see what Hawlucha and Noivern are up to
All I want is a proper lab episode and for his reserves to return when Ash upgrades to a higher ranking so his Galar team gets a chance to shine before all the popular mons like Sceptile, Charizard, and Snorlax come swooping in to do what Pikachu is already doing to the rest of the team
