So you were his...kid. Or his "Morty", as he liked to call you He kidnapped you when you were little, he had also erased your memories before him and therefore you no longer remembered your old life, you didn't even know if what he called you other than "Morty" was your real name.

You had been with him through abuse, mistreatment and horror all your life, isolating yourself from the world. You had not had communication with anyone else apart from him and that was driving you crazy He also used you as a decoy to get information from the Mortys about their Ricks, so he sent you to that universe with a headset where you could hear him and he could hear everything around you

Today was one of those days. You had to leave the classroom because you had received a call from Rick

"Hey Morty, what did you get from the other brat?"

He asked you as you went into a bathroom stall at school
