I really do hope they don`t end Satoshi`s journey here, to be honest I really think it`s far too soon, we`ve been with this show for so long, there`s no reason to stop.
Aside from that, this episode was one of my favourites in a long, long time. The introduction of such an ominous character, even controlling a Darkrai, with such litte information really provides some phenomenal suspicion and foreshadowing. Additionally, seeing Heracross, one of my, if not my favourite of Satoshi`s Johto Pokemon battle in close-combat using Focus Punch like that was incredibly fun to watch. This is becoming what seems to be the greatest Pokemon League Tournament, Satoshi is even splicing in his older Pokemon with his new, and the story is better than every before. I`ll definitely be watching this episode again in the future.
