TF141 has been looking for the traitor, they thought Y/N is the traitor though you werent but noone believed you, not even Simon.

They torture you in a room, Simon was in another room hearing everything, begging that you haven't done anything. Simon loved you, trying not to cry as he puts on headphones so he wont hear your shaking scared voice.

Your begging got louder and then he hears a loud gun shot. Simon3xs eyes widen and fill with tears, he didn't know they would go so far to kill you..
