Mirror Steven Can be a Confusing AU. Here are the important details: Steven is in the place of Lapis Lazuli, trapped in the mirror for thousands of years. In this AU Steven can poof, and he does not age in the mirror. His gem is placed on his back, and Lapis's on her navel. Steven's gem weapon is wings, and he can control plants, just like his mother used to be able to. Steven is half-gem, and his mother, Rose Quartz, never rebelled. Pink Diamond was never Shattered. Instead it was Pearl and Garnet who rebelled, who later found Amethyst. Connie associates with the crystal gems to protect the planet. Greg, Steven's dad exists thousands of years ago and is not a rockstar, but a writer.

Thousands of years ago:

Rose Quartz had been sent as a guard for a Nephrite, whose job had been to check up on the status of the Cluster. Together they traveled to the kindergarten, and Nephrite went into the underground room by herself, while Rose waited by the door obediently. Rose hated her position on homeworld. Recently she had realized that the diamonds don't care about their gems, they only cared about themselves and their power. Rose didn't like being mistreated like this. For the longest time she wanted to do what she wanted to do. She wanted to be free.

As Nephrite tinkered around in the underground room, Rose noticed a human man walking by.

"Hello, Human!" She whispered.

The human looked over, confused. "Hello! Do you know where this place is? I am documenting mysterious places such as this one."

Rose thought about approaching the human. But then would be disobeying Nephrite! Also, did she really care? She wanted to do what she wanted for once.

Rose stepped over to the Human. "Yes. This is the kindergarten. What is your name, Human?"

"My name is Gregory DeMayo, but you can call me Greg. Who are you?" Greg looked her over, and blushed.

"I am Rose Quartz. I know all about this place, I could help you if you wanted." Rose hoped he did want her help, she liked this 'Greg' already.

"Of course I do! Come with me!" He said hopefully.

Rose thought. Did she really want this? She would leave her entire life behind, but what was that really? She could be free with this man, helping him write, and she could make her own choices with him. She would be free! And She would have somebody to be free with!

"I will!" She smiled.

A Few years later:

"Greg! I would like to discuss something with you."

"Yes, Rose?"

"Do you want to have a kid?"

Greg blushes. "Um... Yes? Maybe? Why?"

"I would like to. The idea of creating a life... so extraordinary!"

"But you told me you're a gem. Doesn't that mean you can't reproduce?"

"I would become half of the child, Greg, but I'm willing."

Greg falters. "Rose... Rose, I can't lose you!"

"Oh, Greg... You won't lose me, I'll always be with you."

"It won't be the same! Are you really sure you've thought this through?"

I have thought this through, Greg. And Of course it won't be the same! It will be extraordinary."

Greg sighs. "Rose, do you want this,"

"I'm sure I do."

"Okay. But can we wait a few years, just to be together?"

Rose smiles. "Of course, Greg. Thank you."

Four Years Later:

Greg watches as his beloved fades away.

Thus, Steven Quartz was born, and it was both Greg's happiest and saddest moments.
