I still don't like Harley very much, he can be quite the jerk. At least this episode had some great May/Drew moments. If I can say anything good about Harley, it's that he's making really good material for contestshipping.
Even though May nearly messed things up completely for getting further in the Grand Festival, I think she did do a good job with Skitty. Seeing all the different attacks was pretty interesting (I do love assist), and I liked the comment that it showed the abilities of May's different pokemon. The reaction to the solar beam from out of nowhere was pretty funny too.
[SPOIL]Given that Munchlax knows metronome now, I wonder what would happen if Skitty got that if she was still on May's active team and used assist. That would be interesting. LOL I'd love to try that with a skitty and a togepi.[/SPOIL]
Also, Jessie having to impersonate Anthony was pretty funny. I liked James, Meowth, and Ash's reactions when swalot swallowed Jessie.
Overall, 8/10, knocked down mostly because of Harley.
