I know in the Japanese version it says Butterfree "died" but I'm choosing not to believe it, Butterfree is still with the pink Butterfree and all of their lil baby Caterpie in my head.
Yes, that fact that Butterfree die after mating was troubling to me, especially since I decided to bring Ash's Butterfree back in my fanfic... But I agree with Pokemonisgr8 on that one.
This was also one of my favorite episodes, and the saddest next to "Pikachu's Goodbye". For a long time, Butterfree was my favorite Pokemon, so I felt badly for it.
-Brock did a lot of funny things in this episode. I liked the part where Brock fell in love with another Butterfree trainer and blushed severely... That was hilarious! And fter that, he told Ash's Butterfree to pick the Butterfree that girl released as his mate! "Don;t you get it? When two Butterfrees mate, thir trainers can fall in love too!" (or something like that) Also, when Butterfree got shot down, Brock dramatically said, "I should write a book about the secrets of love and heartache!" And Misty replied, "And I guess that book would be your autobiography?" I laughed so much after that line...
-Another thing I liked was the part where Ash's Butterfree tried to charm the pink Butterfree. And, I like the part where his eyes turned into hearts and he darted off towards his love.
-Another thing I enjoyed was the first battle with Team Rocket. First, Misty sent out her Starmie, but Jessie used a hammer (not a Pokemon) to KO Starmie. That was funny... And, Butterfree tackled them, which I thought a paradox for such a cute little thing. And I enjoyed the part where Butterfree tackled the net several times to release the other Butterfree. I almost cried there because of the drama.
-And, finally, I liked the part where Ash and Butterfree said their goodbyes. That part was, in my opinion, the saddest scene in Pokemon history. It even had a flashback of Ash's time with Butterfree, ever since it was a Caterpie! That was sweet... all set to sad music and a sunset... I cried there.
Yes, that's #2 on my favorites list. (I won't tell you what #1 is, just to prevent flaming.)
