That guy....

Exactlyyyy. Like, how was he able to go into the ghost domain? Everyone else (who doesn’t have the ability to see the deceptions) we’ve seen so far has been dragged in. Hanhan, the other kids in the sewer, Xia Zhao—all brought into the domain by a force existing inside it. I’m thinking that he’s either a ghost himself or he’s behind it. I’m kinda leaning towards being behind it (although the doctor is VERY sus) bc 1. he does not seem helpful in the slightest 2. that person on the phone said “I’ve sent the bait” (Xia Zhao) and this dude, who’s supposed to be watching over Xia Zhao, was just conveniently taking a nap when he left the hospital

WAIT maybe Dr. Xu could actually be innocent and the actual person behind it is framing him? He might’ve been the nurse’s s/o (picture in the wallet) and someone was jealous of him bc they wanted the nurse to themself. In her work log, the logs mentioning the doctor are all scribbled out besides parts that make him come off as a bad person. If he was responsible, why would he scribble the rest out? So actually scratch my other response out, I think it’s bed 14 (other dude is still sus tho)

Yeah I also think Dr. Xu is innocent and that guy might be the one framing him and I don't think the person he saw in the ghost domain is really Dr. Xu or maybe it is but he's there because he's trying to find out who killed the nurse

Omg Dr. Xu looking for the killer makes so much sense. The nurses said he’s been seen looking suspicious in the hallways at night and that might’ve been him looking for a way to get into the domain (even if he didn’t know that’s what it was exactly). Maybe he had nightmares like the patients and Xia Mo did?

Or probably saw something. The part about him being interested in the nurse could be true and maybe he noticed something weird about her before the incident or he saw something that made him realize something not right

I just hope he didn’t have to witness her get murdered </3
