The vibe I got from Clay is that the whole of driftveil was low on revival herbs and he was on a mission to retrieve some more (it is now Ash's responsibility, but that is beside the point). So I think it was perfectly acceptable for Clay to put off the gym battle for his town. This is also supported by that some gym leaders are sometimes seen as Town leaders.Eh not a bad episode felt a little rushed at parts. I have a few minor nitpicks the whole emphasis on the "Revival Herb" just feels shoehorned in especially since it's such a hot commodity that everyone needs. Clay refusing to battle again just because he doesn't have any "Revival Herbs", that's just lazy writing to get our protagonists to the island, we've never seen gym leaders unable to accept challenges before cause they don't have a special item. Also Iris for a medium just because she's a girl & looks exactly like the in the old tale, we really couldn't insert another female character that happens to be descended from the original, if being a girl & having a Gothorita are the only requirements for summoning Landorus, then why didn't TR do that from the start?
Surprisingly enough, I think I have to agree with you. Now that this arc no longer has any expectations attached to it, it's possible to enjoy the two episodes for what they are and not be disappointed.I liked this episode a lot better in the dub for some reason. I can't explain it. I'm satisfied with the battle between Tornadus and Thundurus so far.
