On Authors, Lying and Retcons

Before I begin, I may as well clarify the title and say that no, I'm not angry at authors saying one thing and then writing another.

I was going to post an edited version of my OCs profiles, as there is some information on them that I either don't want you to have just yet (like Golden Sparkles cutie mark and talent) or wouldn't make sense without the proper context.

One piece of information, I need to keep hidden for a bit. I'm not going to say what it is, but I'm keeping it hidden for story reasons. If you don't like writers misleading you, then please turn away from my stories. This will probably be your only warning.
