The front had nothing menacing, big white block, automatic door and the name "tranche-corp" on it with the symbol.

Pearl: So here the plan: Going in, finding the alternate Steven, retrieve all gem equipment we can, sending him back to his dimension and destroying the forecast hall for something like this to never happening again. She looks at us. Any question?

Amethyst: What does the logo mean?

Pearl: It's irreverent to our mission.

Garnet: You have no idea.

Pearl: Let's go Human people! She abruptly said.

The inside is what you could expect from place like this, I think, I never being inside a scientific building, it was clean with exposition of they're newest discovery, pictures of the world with inspirational quotes. It looks like they had a lot of visitors today, so it was easier to blend into the masse.

Guide: And that way you can see the prototype to our space travel division.

Pearl: Their cleary missing an energy compensator, otherwise it will damage the entire structure. Plus is really inelegant.

Rose: You mean you can build a spaceship?

Pearl: With the right material I could but...

Steven: Shhh stay focus we need to go deeper inside without being noticed. I whispered.

Garnet: Don't worry Amethyst is taking care of that.

Rose: She looks around. Where is she anyway?

Like for answering her question, a giant t-rex purple appears out of nowhere and roars loudly.

Purple t-rex : YAAAAA PEOPLES ! YOU SHOULD RUN AWAY BEFORE I GRAB YOU WITH MY TINY HANDS! ROARRRRR!

Rose and Pearl ran in a corridor, Garnet and I in another.

Steven: What do we do now?

Garnet: Our priority is to find the other Steven.

It was like a labyrinth inside. Luckily there was plans and Garnet future vision. We turn left, right, right again, left. When we arrive at an intersection we start hearing explosions.

Steven: Don't you think Amethyst is doing a little too much with the diversion?

Amethyst: A least it works.

Amethyst a just appear to the left lane.

Steven: Wait. If you here then what is...

Another BOOM shakes the ground, and it seems to get closer. When we see the other me rushing to us.

Amethyst: I thought you said you won't explode anything.

I don't think he heard her because he was screaming.

Steven p: SQUARIDOOOOT !!!
