Here is my next one.
This is what happens in my Pokemon Mystery Dungeon fanfiction.
Callum (Riolu) exposes his Autobot identity to escape from Dusknoir and the Sableye. Later at Sharpedo Bluff, he tells Pikachu and Grovyle about what happened.
Dialouge is below the pic.

Callum: It's time I told you the truth... I'm also a human Autobot.
Pikachu: A human Autobot? Why didn't you tell us before? We didn't know!
Callum: I know. And I'm sorry. I didn't want to expose my identity. But when we were surrounded by Dusknoir, his Sableye and Primal Dialga, I had no other choice.
Pikachu: Did you know about this, Grovyle?
Grovyle: No. I did not. When we were partners saving time, I didn't know until now.
Callum: That's not all. I also live in a world of ponies called Equestria.
Pikachu: Ponies?
Callum: Yes. It's a long story, but I'll try to tell you as much as possible why I live in Equestria and how I became a human-robot.
