Beach City.

Blue Pearl walked down the streets of Beach City. She had taken it upon herself to do the weekly shopping and currently held the list given to her by Pearl in her hand. She planned to collect the shopping, storing it in her gem, and then go and read the book Steven had given her in the park. A few residents greeted her as they passed. She noticed some children try to get their parent's attention, as they pointed to the "Blue lady". B.P. smiled in amusement at the wounder across their faces upon seeing her, and she chuckled at the thought of there expressions, upon seeing more inhuman looking gems.

Little did she know a little, round, blue lady and a giant, broad, yellow lady were near by.

Soon.

Blue Pearl was now leaning on a tree while she read her book in it's shadow. "Excuses me." A small voice called her. Blue Pearl looked up from her book to see a small girl. "Do you have a little sister?" She asked.

"I guess you could say I have a sister, but she's older than me." Blue Pearl answered in confusion.

"Oh. Well, you're a lot taller then she is." The girl responded. "Her friend is very big."

"What?" Blue Pearl thought to herself. Herself and Pearl were designed to be the same high, and with the positions they held, there was no room for error in their creation.

"She's looking for you, you know." The girl mentioned.

"Do you know where she is?" Blue Pearl asked curiously as she closed her book.

"I saw them on the boardwalk." The girl answered.

"Thank you." Blue Pearl placed her book in her gem and ran towards the boardwalk.

"There you are." A voice called, bringing her to a halt. It was frightfully familiar. Blue Pearl's shot towards the origin of the voice, and she staggered back in fear. It was a Aquamarine, with her tear drop gem beneath her left eye. Behind her stood a Topaz fusion with a gem on each ear. "You are to come with us back to Homeworld for your trial. And then be fixed by the Diamonds." Aquamarine instructed.

Fear shot through Blue Pearl. "This is it. I'm going back to be punished" She thought to herself as Topaz approached her. "Wait a minute. I'm a Crystal Gem. I'm not going anywhere!" Topaz reached for Blue Pearl, but she took a step back. "No."

"What?" Aquamarine questioned.

"I said no. I am never going back to Homeworld." Blue Pearl growled.

Aquamarine giggled. "You act like you have a choice. Topaz, get her."

Topaz tried to grab Blue Pearl with both hands, but Blue Pearl jumped herself into the air, and landed a few feet away.

Aquamarine let out a sigh. "Looks like I have to do everything myself." She took the ribbon out of her hair and turned it into a wand.

Blue Pearl was aware of what Aquamarine was planning to do and leapt behind a building. B.P. summoned a sword and began to plan her retaliation. She caught a glimpse of several on lookers, and realised the didn't know what was going on. She needed to lead then to a quieter spot. She also needed back up. The Temple will do.

Aquamarine soon hovered above and fired her wand at her. Blue dodged the beam and it enveloped a paving slab. Aquamarine lifted the slab and slammed it into B.P.'s back as she ran away. Blue Pearl collapsed onto the floor with the rubble of the slab around her. Several onlookers gasped in shock at the scene before them. Before Blue Pearl could get up, a beam covered her and she was lifted from the ground.

"No!" Steven cried out before his shield hit Aquamarine in the face, causing her to drop B.P."

"Ow!" Aquamarine cried. "Topaz! Deal with the human!"

Topaz summoned her pugil stick and calmly approached Steven as he summoned a shield. Topaz took a swing at the shield, causing to skid backwards. "He doesn't have the full strength of a Diamond. At least not yet." Blue Pearl thought to herself as she slashed Topaz's stomach. It wasn't a deep cut but it was enough to make her stagier back as she recovered. "We can't beat them alone." Blue Pearl mentioned as she wrapped her arm around him and leapt into the air. She continued this until they arrived at the temple. They sprinted to the door but couldn't see anyone inside.

"Where is everyone!?" Steven panicked.

"Aw are we all alone?" Aquamarine taunted from behind them. They both instantly tried to flee as Aquamarine fired her wand once more, but only B.P. escaped.

"B.P.!" Steven cried out. Blue whipped her head around and saw Topaz approaching. Blue Pearl realised that she was dragging out the inevitable. If they was going to win something drastic had to happen. and she knew of only one other trick. Blue Pearl summoned a dagger and threw it at Aquamarine, before running to Steven. Aquamarine dodged the dagger, but released Steven.

B.P. snatched Steven from the air. "We only have one way out of this." She mentioned before gem began to glow.

Steven recognised the gesture and nodded. "Okay." He responded as his own gem glowed. A pale blue light burst-forth from the pair and a Rainbow Aura Quartz was born. They were wearing Steven's clothes, but the sleeves and leggings had blue cloth on their ends. They wore flats, like Blue Pearl's. Their midnight blue hair was short and frizzy, covering their 3 eyes (. Their skin was a ocean blue. Aura summoned Steven's shield and Blue Pearl's sword. She then banged the sword on the shield, creating another sudden burst of light. The light soon revealed a curved, light blue blade. "Leave." They commanded in a feminine voice. With a thumb on the outwards facing side of the blade and the index and middle finger on the other side, they revealed the blade to be a war-fan. "This is your only warning."

Aquamarine laughed at them. "You think forming that disgusting fusion will save you? Topaz! I've had enough of this planet! End this." She commanded. Topaz stepped forward, and Aura summoned another war-fan.

Topaz raised her pugil stick, and Aura threw their war-fans at the apposing gems. Aquamarine dodged the blades while Topaz deflected the war-fan. Neither opponent saw the brief smirk on Aura's face before the summoning 2 more war-fans and engaging Topaz. Aura focused more on dodging rather than blocking.

Aquamarine soon got board and aimed her wand at the cross-fusion. The sound of something cutting through the air caught her attention. Aquamarine only turned in time catch a glimpse of the war-fan.

Poof!

Topaz instantly look at where Aquamarine was once hovering. The other war-fan sliced the back of Topaz's legs, causing them to give way. Aura crossed their blades across Topaz's neck.

"Please." Topaz begged. "Do you whatever you want to me, just don't hurt Topaz." A tear rolled down her right check. Followed by one on her left, and they just kept coming. Aura dissipated their war-fans, and offered her their hand.

"There is a better way to live than this." Aura announced. Topaz whipped her tears away accepted the offer.

"Thank you."

Later.

The warppad actives to reveal the other gem occupants of the house. "You're back!" Steven cheered.

"Finally." Blue Pearl commented with a smile.

"There's some you need to meet." Steven mentioned, but nothing happened. "That's your cue." He whispered.

"Oh, right."

"It can't be." Pearl muttered.

Topaz came around the corner twiddling her thumbs, and looked extremely shy. "Hi." She greeted in a quiet voice.

"Sup?" Amethyst responded with a nod, before she stepped off the warppad, to the kitchen.

"Sooo, do you want to be a Crystal Gem?" Pearl finally spoke.

"Maybe. Right now I just want to be me, with no one interfering." Topaz answered.

"Take as much time as you need. We'll be here when you are ready." Garnet answered with a smile.

The next morning.

"Steven. Steven." Pearl gently called to the sleeping the hybrid.

Steven slowly stirred, and saw both Pearls stood over him. "Morning." He greeted while he rubbed his eye.

"Steven, there is something very important that you need to know." Pearl announced in a even tone.

"It is something she has wanted to tell you for a long, but has only recently been able to, and has been trying to find the best way to tell you." Blue Pearl mentioned from behind Pearl.

"Okay, what is it?" Steven asked.

"To give you better understanding, we need to start when I still served Homeworld. When I served... Pink Diamond."

The End.

I felt this would be best left open ended.

I had originally planed for the war-fan to be B.P.'s gem weapon when I realised it would be better as a fusion weapon.

Aura is just the name I found when searching blue rainbow quartz to see if they were actually a thing.
