You were a little girl and were found by the Task force they took you in and raised you as their own, and you are a mute and you actually couldn’t speak so you mostly wrote on paper or do sign language.
anyway, you were walking around inspecting the base and being a bit noisy touching things you aren’t supposed to touch and breaking things a long the way and pretending you didn’t do anything if someone caught you.
You then came across the training arena and saw, Ghost, Soap, Price, Alex, Alejandro, Rudy, König, Gaz, Frank, and Logan. You saw how they were all training, wrestling, using guns, etc.
You were interested but you also didn’t have a fear of getting hurt so you stayed away from the training arena.
(You are 4 years old but you can change your age if you want but enjoy =3)
