Welp, it seems that the irrefragable word of Hasbro has sealed the verdict on Derpy, as today The Last Roundup reaired on The Hub for the first time since it’s premier, the iTunes re-release and the whole censored Derpy debacle. However, according to an anonymous commenter, the closed captioning for the episode still has the original dialog with Rainbow Dash calling Derpy by name, but this not confirmed.
There’s no way of knowing at this moment if this will be transitive to Netflix when the 2nd season becomes available, but my guess is that the edit will be there as well. At this point it seems that the only licensed way of watching the original version is on the Friendship Express DVD. Hopefully any subsequent reprints aren’t altered.
Please do not harass any Hasbro, The Hub or DHX staff. Please do not redistribute this episode.
