It seems like the price for the tag battle is a smoothbell? It looked like one. Maybe Hikari wins and uses the bell for her bunny...you know..the bunny that evolves through happiness.

She needs to win anyway since she was so upset after the contests loss. But I guess she already is back to normal thanks to Mr. Glasses.
The tagbattle episode was awesome! just awesome. And the next episode looks like it´ll be filled with DRAMA and with a little bit of shinning floor. I miss Maestro xD
So many dialogues in this episode that I really want to hear translated. What was the deal with the girl and Takeshi? Why was he so upset? Is she settled already? He was so cute when he grapped her hand after they won only to be all shy about it directly afterwards...
Mr. Glasses is pure awesomeness as well.
Oh, and I really liked Scyther´s and Magmar´s voices ^^ or koffin´s expression when its rapidspin(?) was stopped by psychic. priceless. Or elekid´s attitude towards pikachu...
The battles were very nice as well, but what I really liked was the character interaction.
It is really interesting that the writers finally handle the plot less episodic. Talking about Shirona, Satoshi copies techniques from contests etc. DP is very suprising thus far ^^
