I really enjoyed this episode, especially all the character interations. One I particularly like is the Iris, Dawn relationship which seems to be developing. It appears that Dawn is following Iris slightly but I hope it doesn't develop too much as I fear we would lose some of Dawn's memorable traits. I also enjoyed seeing Onix as we hadn't seen them in a while and the shiny Onix just added to the enjoyment, but for some reason I was hoping that Ash was going to mention the Crystal Onix. Finally, I wasn't expecting Meloetta's forme change into her Pirouette forme but it was great all the same.
Anyway, on to the next one!
