Well, given that Rose has a pink diamond in her hands, and WD's presence (who seemed to be absent for the most part, given that it's not her colony. Presumably the other didn't arrive until after the war started to deal with the rebels), I can't agree. What is this supposed to be? A prophecy?
Hold on... that's not white diamond in the image. It looks like her but the gem is in the wrong place. It's not Pinkie, YD or Blues either either. Who the hell is this?!
