Peridot used the warp pad to arrive at the Crystal Gem temple. She was holding the two mirror stone gems she was asked to watch.
Peridot: I wonder if my improvised scanning equipment would work on these gems. I need to know all about them. Hopefully, they don't mind me coming here. I mean I did leave a note, did I? I'm sure I did.
Peridot went into Steven's house and into the bathroom where she was greeted by her living Pumpkin. She then placed the mirror stones under a scanning device she put together out of anything she could find and scanned them for information.
Peridot: Fascinating! Unlike any gems I've seen. I have to give the Zrit credit for this. I don't think homeworld would ever come up with something like this if they tried. Huh?
Suddenly, one of the stones started floating up.
Peridot: Whoa! This one is forming. I better take notes of this.
She got a video camera out and recorded the Mirror stone taking its form. It did appear in the same form as the others but with his gemstone on the back of his neck. He then looked around confused and then at Peridot.
Peridot: Hello there. I assume you are M4. Allow me to...
But M4 then sees the Yellow Diamond symbol on her chest and freaks out.
M4: Ahhh!
M4 then ran out of the bathroom.
Peridot: Wait! What...? Oh right, I need to get rid of this symbol.
She and the Pumpkin chased after M4 who ran out the front door. They get out and see him running on the beach.
Peridot: Wait! It's not what you think! (Groan) Jet is going to poof me for this if I'm lucky.
It was night in Beach City. M4 ran into the town but is scarred by everyone around him being so timid. He kept screaming and running any direction until he found somewhere that looked safe. To him, it looked like a fat land vehicle with a nice paint job. He dived into it and took cover under some blankets.
A few minutes later, Greg Universe walked up.
Greg: Ah man. Did another animal get in my van?
He carefully opened the back doors and saw a pair of eyeballs under blankets. It was shaking in fear.
Greg: Oh, I guess it's someone's dog.
M4: What's a dog?
Greg: Oh, I guess it's a kid. What are you doing in my van?
M4 could see he was friendly and less scary than the other people.
M4: This thing felt safe. All the other organics around here are scary.
Greg: Well, my van is cozy so I can't blame you for that. Now, which ones scarred you?
M4: Some dark-skinned male yelled at me for being near his shop, some fat one with curly hair kept saying I was weird and then there is that one over there starring.
Greg looks and sees it was Onion standing there eating chips.
Greg: Well, some are...difficult to get used to but they are good people. You should see my son. He knows how to...
Peridot: Greg!
Peridot ran up to him and M4 ducked back into her blanket.
Peridot: Greg! Have you seen a grey boy come through here?
Greg: Well, there is one hiding in my van. He seems scared of everyone.
Peridot: That must be him!
Greg: Who?
Peridot then took the time to explain the situation.
Greg: Wow! Here I thought my boy would be the only male gem. Well, I think I know what to tell this kid.
He then went up to his van where M4 was still hiding.
Greg: Kid, it's alright. Peridot isn't working for Yellow Diamond anymore. She is a...what's a nice word for "traitor"?
Peridot: There is none.
Greg: Well I can tell you she can be odd and was hard to get used to at first but she's alright now. This is from someone who she pushed off a roof once.
Peridot: I was wanting to see if he had flight capabilities.
Greg: But she is good. Or at least trying to be.
M4: So, she won't take me to the diamonds?
Greg: Of course not.
Peridot: We're kind of cut off so I couldn't if I wanted to. WHICH I WON'T!
M4 did trust Greg's word and soon started to get out of the blanket. But then Pumpkin came up to him barking and he hid again.
Peridot: Oh! That's Pumpkin. You don't need to worry about him.
M4 then looked at Pumpkin and then smiled.
M4: Oh! It's a domestic organic pet!
He then gently pet it and Pumpkin liked it.
Greg: Peridot, is there a reason this one is so timid and easily scared?
Peridot: I don't know! If it's like homeworld gems, his personality is random and the diamonds would only care if it gets in the way of their duties. It was the same as that group of Rubies we dealt with before.
Greg: Well, it would make things more interesting. No one wants people to be the same.
Peridot: I can see that.
Then something caused the van's radio to turn on Greg's old songs surprising all of them.
Greg: Oh man! The radio is still turning itself on somehow.
M4 was going to hide in the blanket again but then somehow liking the sound of the music.
M4: Oh! Is that music? Cause it sounds great!
Greg: Oh! Do you have a thing for rock?
M4: What does rocks have to do with it?
Greg: No, that's the name of the music genre it is.
M4: OH! Well yeah!
Then Peridot just remembered she left the remaining mirror stone in Steven's house.
Peridot: Uh-oh! I think we should go to them. Quickly!
M4: But I wanna hear more of the...
Peridot then grabbed his arm and ran pulling him towards Steven's house.
Later, Peridot, M4, and Pumpkin came back to the house. Peridot ran into the bathroom and saw the remaining mirror stone was gone. She was about to panic but then remembered M4 was there and didn't want to make him panic.
Then they hear snoring from where Steven's bed was and went up to it. They see someone in the bed sleeping. Peridot carefully moved the cover and see the back of the head of what looked like a Mirror stone in its form. But then the boy in the bed groaned and pulled the covers back over him with his right hand. They were able to see the gemstone on the palm of his hand.
M4: Umm...
Peridot: M5 I presume?
M5: Go away! I wanna sleep!
M4: You do know we don't need to sleep, right?
M5: I don't care. I like it.
Then appearing from the warp pad was Steven, the crystal gems, Jet and the other three Mirror stone. Jet saw Peridot and M4 and ran up.
Jet: There you are! Peridot, why did you leave without saying something?
Peridot: Didn't you see my note?
Jet: No! Was it paper? Cause it was windy out there and may have blown off.
Peridot: Oh! Oops!
Jet: Luckily, Garnet's future site showed that you would be here with the other mirror stones.
M1: Couldn't she have known Peridot would take the others here to begin with?
Jet: Maybe but at this point, I don't want to know.
Garnet: Actually...
Jet: I said I don't want to know!
Later, Greg came into the house to see everyone there. The mirror stones were talking together. Of course, they left M5 in bed cause with the way he groaned they were too afraid to touch him. M4 saw Greg and smiled.
M4: There he is. The one with the vehicle that played the cool sounds.
M2: Oh yeah! Something about rocks?
Greg: You must be M4's brothers. Well, I can tell he was interested in my music so I got him this.
Greg then got out a tape of his songs.
M4: Oh! What is that?
Greg then placed it in an old boombox and played it letting him hear his music. The Mirror stones were soon bobbing their heads and smiling.
M1: Whoa! That is cool to hear!
M2: Yeah, but seriously what did rocks have to...?
On the other side of the room, Jet talked with the Crystal Gems.
Jet: It's good that all Mirror stones are all safe and accounted for.
Pearl: So what will you do now?
Jet: Now sure. For now, we are going to work on getting our salvaged equipment working and try to contact the Zrit command. It would be difficult cause even if we get our relay working we will still need to keep Yellow Diamond's forces from intercepting our signal.
Peridot: Well, they don't listen in this area anymore since they gave up on Earth. But not sure about the area near the Zrit world.
Jet: Yeah. Who knows if the war is still going on. We can not let Yellow Diamond know of the Mirror Stones. They will stop at nothing to get them.
Pearl: Best not to bring this up with them. Don't want to break them out of their joyful music session.
Amythyst: There are plenty of things to worry about here.
They then hear M4 scream. They see him hiding behind M2.
M4: It's back!
They see Onion just standing there in the doorway eating his chips.
Steven: Onion, go home.
