THEORY 1: NOAH'S DOCTOR IS THE KILLER
- the first time the doctor appears, his face was always obscured or hidden. It feels intentional and unsettling
- Noah pointed out that it was odd that the doctor didnt pick up on her hallucination symptoms
- the killer seems to know about the ins and outs of the mansion and even the names of the family members (but this could be just bc Linda was helping him)
- Linda seemed oddly interested in Noah’s treatment. What if she suspected the doctor was hiding something from her too?
THEORY 2: LINDA HAS HER OWN MOTIVE
Linda (when she was alive) was investigating something connected to the doctor, possibly uncovering his true identity, involvement in past crimes, or maybe to protect someone or revenge?? This lead to her death bc maybe the killer caught her. And then maybe she had no choice but to allow the killer to take advantage of her as a ghost so she could realize her motive. And then in comes Noah. Maybe knowing more about Noah's "hallucinations and treatment" is significant for Linda's motive. That's why she kept asking about the treatment or, again, it could be she suspected the doctor was hiding something from her too
THEORY 3: THE KILLER IS CONNECTED TO NOAH'S MOTHER
Other theory I have is that the killer is also linked to the death of Noah's mother. She didn't actually go insane and kill anyone. Maybe she was also being deliberately framed by the killer, just like Noah. BUT the reason why the killer is setting up Noah and her mother is still a mystery. Maybe this is where Linda and her motive comes in.
THEORY 4: THIS COULD BE A STRETCH BUT STAY WITH ME
The killer is not the doctor but someone that was dear to Linda when she was alive (lover?). That's why she's allowing him to take advantage of her. BUT at the same time cant put up with it anymore and wants him to stop thats why Linda is sticking to Noah. This also checks why Linda was oddly interested to know about the treatment because she wants to "treat" the killer so he could no longer see/hear ghosts
