Halfway through the season, halfway done with rewatches.
Is it some kind of requisite in this anime for a Pokemon to defeat its evolved form when pitted against it? I'm not saying this battle was bad, but man, am I ever sick of that device. I find it a little odd that we have not seen Kengo's Alakazam since this episode, but I suppose the entire penguin line is too much for the writers to resist. Pachirisu's appeal is done well, showing that Hikari is still a beginner and that they aren't interested in rushing things with her. It was nice seeing Dokucale again - a precursor to good things in a future contest (that also involves Kengo, coincidentally).
The culminating battle is pretty decent, as not only do we get to see Pochama strut off Whirlpool (nowadays, I'd kill to see a different attack), but nothing screams total unfairness in spite of the blatant disadvantage. It's nothing truly riveting, but at the same time, it's not Eneko vs. Samayouru. As a contest arc, Sonoo is pretty typical in spite of the vital introduction, and Kengo has never truly interested me since. But it got the job done.
