I liked how they did the really fast recap at the beginning. When I saw this episode when it aired back in 2003/2004, I missed already some the first episodes of the Advanced Series. Now, this episode was interesting and I was like wow, how can this Pelipper have all these attacks. But once it was uncovered, I was like" This guy is masterful when it comes down to cheating"
Also, the whole gym concept reminded me a little of AJ - seeing as both this episode and the AJ episode aired pretty early in both seasons.
