The first half of the episode focused primarily on character development of the evil legendary warriors. While I expected something corny after Arbormon's work-out rhyme, the dialogue did very well. We find out that Mercurymon, though evil, is not entirely loyal to Cherubimon. He's in it for himself. Also, the rarely-seen Duskmon gets his share of development. Is he really evil? Is he actually on the goggle squad's side? We aren't quite sure at the end. And there was an argument between these two that was so good it was out of character for the series.
"I will not be made sport of, Duskmon!"
"I was clearing my throat."
"Well, aren't you self-centered?"
"Master Cherubimon noted your absence at the meeting he requested."
"Just because Cherubimon gets you three to obey his requests doesn't mean that you are truely loyal to him."
"Bite your tongue!"
"Do you deny it?"
"You dare to question our loyalty, you jackanape? You, who have never even set foot on the battlefield? Well, perhaps the little humans be too much for you."
"I see what you're doing, getting Ranamon and Arbormon to do the menial labor while you wait for the right moment to strike."
"Those are strong words for someone whose actions are so weak. You are a coward!"
The second half, on the other hand, is a great big ol' fight scene between Pedaldramon and the good guys. And what a fight at that. It's not often we get to see one that is unbiased, so to speak. Each character plays an equal part in it, with not one outdoing any other (as it has been pretty much all the way up to this point). After a painful start to the brawl, Koji gets the first good shot in, giving Tommy the oppourtunity to start picking up Pedaldramon. JP then defends Tommy from Pedaldramon's Thorn Jab, giving Tommy enough time to lift and throw Petaldramon on his back. Takuya and Zoe finish him off with a combined Wildfire Tsunami and Hurricane Gale, and Koji then scans the beast spirit of wood.
The team gives Arbormon a chance to surrender, and just when it looks like he will, Duskmon steps in. He states that without a beast spirit Arbormon is useless, kills him, and absorbs his data and human spirit of wood. So whose side does that leave him on?
Overall, this is one of my favorite episodes of the entire series. Great dialogue, great story, and great action - what more could a guy ask for?
