Just seen it. Man I really do not like the sound of that episode. I really hate the idea that Kortesu beats Ash. And no, there will be no bridge episode between Unova League and N Arc, because the next week after Lucario vs Pikachu is when the N Arc starts. Man I hate that. So I guess Ash will be the top 8.
Isn't there a break at times between bridge eps? like Ash going to Hoenn and Sinnoh? Thats what I meant by bridge. A conflic connecting to the next series or arc. Like how Pikachu was drained of it's power in the final ep of OS and how that was a "bridge" into AG
