Overall I liked the episode. I agree with much stated above, but have a couple additions:
1. Harley filing his nails. WHY!? He's a guy (I hope), and that look of concentration he had when he did his nails... it was weird
2. The music when Octilary danced. That was just...odd. It sounded a little tropical, but with some birthday party style, and techno mixed in. Again..odd
3. Harley's Improvements on Ocatlary. Well, this goes along with the others, but I do notice its gotten a lot stronger, as Brock stated. It got him on the top row of results on the screen.
4. Harleys Cacturne disapoints. Well, It fainted in like what, one hit? That didn't seem to fit. I think PUSA was trying to get all attention souly on Wigglytuff.
5. Wigglytuff. Well, it was powerful. I liked how Brock mentioned "Thats not someone you would want to meet on a dark alley". That seemed to fit, sence Wigglytuff had that dark patch under its nose. I do admire its strength, but I don't really understand how May beet it, and the way it used its ears to attack was a little strange.
6. Dark Drew. Well, that was a side we've never seen before. I think it added a lot of character to Drew, but at the same time seemed a tad out of character. I mean, he's never lost it like that before, so this was strage. But it did tell us that he's worried May is catching up. And you can't forget that it's a major Contestshipping canon.
Well, thats all I have to say at the moment. I'll be sure to post back once this gets some more replies.
