The shadow assassin (steven universe reader-insert)

Chapter 18.

You: (walks up to steven*) Yes steven?

Steven: Y/N, can you tell my dad all about those homeworld gems that we fought?

You: Well, it's kinda long actually. These other gems just came out of nowhere and beaten us up and- 

Steven: (interrupts*) Then they abducted me, y/n, and the crystal gems onto the ship because they wanted to take me away forever. And then we crashed the ship and I almost died!

You: (pats steven's hair*) Heh, yeah it was a near death experience.

Greg: (increasingly worried and panicked*) What did they want with you?!

Steven: They think I'm mom

Greg: (stammering*) A-are more homeworld gems gonna come after you? The both of you?!

Steven: I... uh... I don't know. Maybe?

You: Don't worry greg. Me and steven got this.

Greg: (clearly distraught*) Steven, y/n.  I-I'm supportive and very proud to the both of  you. And I'll be right back. (runs back into his van*) Got to calm down. Where's my... (picks up lots of CDs from the back of the van*) Where's my relaxing music CD? This one? (puts a CD in the radio, and death metal music starts to play*) Wrong one! Stop! Eject! (punches the radio and tries to calm down*)

You and Steven watches the commotion as Greg tries to calm himself down, when his phone starts to ring again, realizing it is Connie. He looks back at his clearly-panicking dad as his van breaks down. Suddenly, your gem was aching really badly again you scream loudly because it's really painful it kinda feels like having a heart heart attack.

You: Arghhh!!! (you now look at your gem and it was glowing red*)

Steven: Y/N!! (you now fall to the ground and steven tries to care for you*) Guys!!

The crystal gems look at you fastly and was now checking up on you, greg runs out of his van for a sec and turned the music off. Pearl now removes your shirt a little and was shocked, everyone was shocked. Steven and the crystal gems saw your gem and looks like steven's gem but it was black. Everyone gasp.

Pearl: I-is that? (touches your gem and felt your aura or black diamond's aura*) No it can't be!!

Amethyst: Pearl, what's going on? what's wrong with y/n?

Pearl: (looks at you with deep shocked*) Y/N, where did you get that gem?...

You: (everyone looks at you and was waiting for an explanation*) It was put into my body three years ago. I had an accident and was rushed at the hospital, the doctor said there was no hope for me to live. Unless, they put me this gem. Then after getting out of that hospital, i noticed weird things happening to me recently. I was getting stronger, i was getting faster, and many many more. Remember when those thousand of water stevens attacked and i kill a lot of them. Well i used up some of it's powers.

Garnet: Pearl, what did you feel when you touch y/n's gem? How was it?!

Pearl: (panicking*) It was different, i thought at first it was just an ordinary gem that was stucked on y/n's body. But it turns out...

Amethyst: It turns out about what?

Pearl: It's an aura.. (you and the crystal gems gasp*)

You: What kind of aura?

Pearl: A diamond's aura...

Everyone was horrified at you now.

You: What?! What do you mean "black diamond"? Pearl, what are you talking about?! What do you mean- ARGGH!!!
