I Personally liked seeing them thank you very much :X
At least SHOW me when they learned it, because its not like ash learned those during the match.
I mean, think of charizard and Infernape.
Flare blitz was shown to be learned before the match.
So were steel wing and overheat. Why can't they give us a simple "When they learned these moves?" They've always done that.
And they even did it in best wishes season 1, as you said. Why the sudden stop?
