I thought this was a great episode. It had a great drama, Ash's voice keeps getting better, Sceptile finally relearns his moves. It was a very satisfactory episode. I was also pleasantly surprised by Spenser's voice, it was really good. At least it wasn't the same old man voices we've heard in many old episodes, like with Pryce or with the old men in "Plant it Now Diglett Later". The episode also reminded me a lot of "Challenge of the Samurai", with all the beedrills and kakunas, and Team Rocket's coverage (at least this one wasn't cardboard.
Overall, 10/10. I can't wait for the new episodes Friday.
