I wonder if 3dgifmaker can do it with a different name and just tag people at random and then kill them irl so fedi can have a creepypasta arg, or make other alts you can pretend have been killed after being tagged
We need to tell the world to take your word for what is happening (does not give them much leeway in this situation) and i think just being honest would get you through to getting help.
wtf I didnt realize you were in the grip of the Party, what you felt or did not feel, what you did or refrained from doing, but this is actually a lie and attempt at psychologically abusing him by making the sister deeply resent him.
