Well isn't it because when his eye was injured, it allowed him to see spirits from the other side

lillianna_p:

couldnt he already see spirits

i think it was that he could sense them but not see them?

wasnt it that he gained the spiritual eyes (idk what its called lol) after he had hurt his eyes? thats what he said in the hospital ig

I honestly think he was possessed somehow and spirits are becoming cleverer... That red thread might have got into him at some point. But I think there will be a season 2

She got stuck in the other dimention with the spirits no?
