I've got a huge kanji final exam coming up tomorrow, so I'm not going to have the summary up until after that's finished (roughly early Friday, US time). I do have a few quick notes, though:
-It seems like Brock's Ludicolo's little quirk is that, when it's called out, it instantly starts dancing with Max. Of course, since the pokemon's so much bigger than Max, it just kind of swings it around like a rag doll. Ludicolo does this routine twice in this episode.
-Jessie uses her Dustox and James uses his Cacnea, both for the second episode in a row.
-The eyecatch/Next Episode Preview was changed AGAIN--this time, there was a Regirock theme.
Other than that, it was a standard filler episode. I'll get the details up within the next few days.
