Elise Reiner: Who is she?
Elise Reiner: A parasite. She befriended your astral body and lured you into the further just as Dalton has been.
Trivia: The "Bride in Black" is played by a man wearing women's clothing. This was done so that something would feel "off" about the image of the ghost. At the time, the character was intended to be female. However, when the creators later reused the character for the sequel and added in a backstory, they worked the fact that the character was played by a male as part of his backstory - it actually is a man who masqueraded as a woman as a disguise to lure in victims.
Question: When Josh is in the further looking for Dalton, what is the deal with the family that looks like mannequins and has the creepy smiles? Why does the one girl shoot the family? Is there any back story on it?
Answer: They are just people trapped in the further after their terrible death. It would be nice to later find out the back story on them in a future film.
Answer: It's implied that the girl went crazy and killed her family, but it's not really elaborated on. They're just some of the many spirits to be trapped in and haunt the Further, likely due to the violent nature of their deaths.
