I have to get this off my chest...this is the best lineup Ash has ever had. It really is. I know there's that annoying lack of a fire type, but his current team is really the most diverse and well-assembled team the writers have ever thrown together. Now that the writers have seem to gotten over their fear of evolution, is it still to much to ask that they give Corphish a little help?
As for the episode, it's one of the best there's been in a while. It provides an alternate version of evolution, a less-glorified one, that works terrifically as serious character development for Grovyle. Bravo. Let's hope this keeps up.
