AG89: Arrival in Lilycove City! PokéBlocks and Aerial Ace!? It seems Swellow is still in the mind of the writers and hasn't been banished after it's great battle with Winona. For the PokéBlocks I know May has a case but if I remember correctly she never had any or made any.
AG90: Pikachu, Joining/Banishing Team Rocket!? Im not sure what to say about this....
AG91: Pokemon Contest! Lilycove Tournament!! Should be fun to see which pokemon May will use, after her last contest Bulbasaur has not made much of an appearance so maybe it. Contest are great because they (so far) have always introduced a new pokemon in an interesting way.
However I wish they would have put off getting to Lilycove, I was hoping there would be an episode on Mt. Pyre and the Safari zone.
