So my MC don't realize this at the moment however I think that I may have inadvertently just destroyed his credibility of being able to be trusted as a hero. Has anyone else accidentally done this before?
This is definitely not the flaw he has to overcome, this would be a speed bump compared to how biggest issue of a imp inhabiting his mind, with this construct he just realized this construct is nothing compared to the other one designed to spy that he already fought before. He's being stalked by these objects for some reason and he still hasn't even figured that out yet, only second time fighting these objects and neither was similar the other was humanoid shaped.Also sounds like you have a character flaw your MC needs to overcome later. People love redemption arcs.
