My FNAF AU/Headcanon (Original and Current)
Neighborhood Kids MCI - I don't think the laughing teenager is the victim of MCI; Charlie would basically be the 5th
Phantoms - In the AU, only the hallucinations are the Phantoms (Mangle, Balloon Boy), while the others are ghosts from the MCI who didn't move on
Shadows - I believe they are both separate and neutral entities, difficult to explain
Witness Charlie - BV didn't literally witness Charlie's death; he knows she disappeared (or thinks she was killed), and the rumors about the animatronics made him afraid
As a side note, I'd like to say that... I haven't played and know almost nothing about SOTM, Ruin, and HW2 (it's been a while since I've followed the franchise)
