After 6 intense, emotional episodes in a row, this episode comes as a bit of a relief. It's a peaceful episode, with Ash and Dawn trading pokemon with each other.
Zoey has a pretty good appearance here. She is the one who suggests that Dawn and Ash make a trade, but she does not try to force them when they initially cannot do it. It's a nice little touch of sensitivity from her.
The beginning of the episode continues the trend of Zoey finding our heroes in a weird, slightly embarrassing situation. Ash and Pikachu do their best Shaggy and Scooby impersonations (Pikachu's smile gives the impression that it's in heaven, ha ha). But I wasn't as bothered by it this time since the recent Chimchar episode began with Brock snapping at Ash for complaining about lunch (a funny moment; see, Zoey is not needed to get a laugh); so the scene in this episode did not feel so much out of character.
Zoey smiles at Ash's encouragement of Dawn when Dawn gets intimidated by the tv news of Kenny winning 2 contests (in a row? Shame on me for not taking good notes), and I think it reinforces what happened at the beginning of the Tag Battle Arc, when Zoey asks Ash and Brock to convince Dawn to enter the tournament rather than doing it herself. In fact (hope this is not just a dubbing thing), Zoey remarks that Kenny is really on a role to make the gang aware of her presence, and that really is not what Dawn wanted to hear right then. Ash comes to the rescue by telling Dawn not to worry, as she will catch up and then be better than Kenny, causing Dawn to smile in appreciation (sorry, another one of my favorite Ash/Dawn moments). Zoey's smile in response shows that she is glad Ash can provide that type of support, b/c she's incapable of doing it herself (seems to be against her nature).
To end this review on a bit of a light note, there are a bunch of fun ideas you can apply to Aipom's and Buizel's expressions during the training. My favorite one is when Aipom is watching with a frown as Glameow uses Buizel's water attacks to make a sparkly appeal, as if Aipom is in disbelief that this appeal is being used for what feels like the millionth time. To show real creativity, Aipom makes a swift appeal (and it looked nice, too).
