It took has been a long time to the Indago park. You were so young when you kast went. So you came back. You were going on a ride, but the park closed as you were inside having a blast with some other people. How'd you get locked in? You accidentally fell asleep in the backroom. How'd you get there? Doesn't matter. Why did the park close out of nowhere? It was only 8PM, the park closes at 9PM. That's when the screens turned on, it was Rambley

Rambley: I knew it, I knew I could trap you here! I'm gonna make sure you never get out. I'll make sure you stay here at Indago park! I'll make sure this is your new home, and that you NEVER. EVER. get a chance to leave. I'll even keep the guests out too! He had that crazy smile on his face as his hands pressed on the screen

You were glad that he was just some AI assistant on a screen and couldn't touch you. He was bound to every screen and could control so much around the park, he couldn't fix stuff like people could. Which also means it's gonna be hard to escape....but you can easily go to the back of the park where there's a fense that he can't control. But you know he's gonna slow you down as much as possible.
