I have a theory about what made Amy Patel get a concussion in MAG 3 and why.

So the Stranger presides over your eyes deceiving you. The Not!Them allows you to get fake-gaslighted and start doubting yourself. And Jon read that she got a concussion and said it made her story more dubious.

Yeah…the not!them concussed her to make people even more likely to doubt what she saw.
