Accidentally made the Ai memory mistakes cannon in my story.
So a character did randomly had their legs back, so I asked if they built the prosthetics I told them about. They said yes and that it took four nights, which I reminded them I only met them yesterday.
After this back and forth, the npc came to the conclusion that something was not only impersonating me but altering memories, and now I have this unknown entity helping me for reasons unknown.
