I'd rather be seeing a physical bug attack on Leavanny, like X-Scissor.. I originally wanted his final moveset to be Solarbeam, X-Scissor, Energy Ball and String Shot.. but I could accept Leaf Storm instead of Solarbeam if need be.
But we digress from the topic.. I am personally just happy that Snivy is getting a development episode and that we actually get to see the full extent of her personality again. Whether she gets a new move, or evolves or not is fine by me, as long as she is handled well in the episode overall.
