Wait, what? WhoWhenWhereHowWhy? Trixie originally being a guy I knew about— did anyone ever say what Guy!Trixie's name was?— but I don't remember hearing that the original pitch was way overtime before.Also, yeah, Trixie got shafted pretty hard in Boast Busters for somepony whose stage act was built around BIG TALK, and who did her level best to stand up to a giant freakin' space bear she was in no way equipped to handle; it's not like she was claiming to have been in the Royal Guard and singlehoofedly stopped an invasion or something. I still don't think the Mane Six were being the horrid OOC monsters the episode's detractors usually make them out to be— they were jerks, but not to any superawful degree— but a bombastic performer is absolutely in the right to dress down a bunch of hecklers, and the ease with which she did so made it look like that was just a regular part of the show.
