You took a work subpage title that uses a term the way the term is used in the work, and changed it to use a different term because that's what TV Tropes does.
All The Tropes is as much a reference site as it is a troping site, and using terms that aren't in the source makes this site less useful as a reference.
Also, "that's what TV Tropes does" is never a valid excuse to do the same thing here. The other admins could tell you horror stories about how TV Tropes did things before this wiki was founded. I was never on TVT, but I've literally spent years cleaning up some of the messes that they decided to make, and I'm nowhere near finished yet. Please don't do something just to copy somebody else.
