Save Derpy We have an extensive email from Amy Keating Rogers, writer of The Last Roundup. It explains that the scene in question was actually much longer at first, and Derpy was given her show name, Ditzy Doo. Mrs. Rogers was asked to shorten the scene and give her the name Derpy as a shoutout to the fans.
Having done as she was asked, Mrs. Rogers did not see the episode until after the controversy over the name arose, but she did not have a problem with the scene, other than Ditzy/Derpy's voice was too low. She went online, and found that, for the most part, Derpy refers to clumsy, accident prone, etc, something she felt went along fine with the character.
But, then she found the darker side of the internet, where derpy becomes a much more hurtful word. Having a severely mentally disabled son, it broke her heart to realize the name being used in an episode she wrote.
Now, Mrs.Rogers had no say in the events after the shows airing. She was asked her opinion on the matter, but nothing conclusive was reached while she was involved.
I'm an optimist by nature, I try to see the good in everything and everyone. What I take away from this is our beloved mailmare will never be named Derpy in show again. BUT she does have her show name Ditzy. Plus, her scene was only shortened for time restraints. So I think the writers, animators, etc like her just fine.
So what if she's named Ditzy in show, this could be our chance to get more awesome scenes with her (unedited or edited, its still one of the best examples of a classic cartoon gag I've seen in quite some time.) And nowhere is it written that she can't be Derpy in our hearts.
So guys, I am hanging up my #SaveDerpy hashtags. I am satisfied with the response, and I hope to see more Ditzy Doo in the future. In the end, I trust Hasbro, Studio B, DHX, and everyone involved to do the right thing. We may not always like it, but if it keeps Friendship Is Magic going, I'll get behind it.
