My running theory for MONTHS has been proven CORRECT!!!
My running theory was that because diamonds cant be shattered, especially not by a weapon that has been specifically stated to not be able to shatter gems, pink diamond came to earth and fell in love with her colony. So because it wasn't acceptable, which is clear from the behaviour of the other diamonds, she decided to fake her own death and live on the colony she loved so much. AND IT FREAKING TURNS OUT I WAS RIGHT!!!! I am so freaking proud of myself because I figured it was a long shot but it made the most sense. Holy... I was right. I cant even believe I turned out to be right. So steven is pink diamond. heheheheheheheh lets see where this goes. <3 <3
