No visions of victims, no knowledge of Djinn
I thought it was interesting that the djinn in this one (presumably having learned a bit) , went with a new strategy by choosing not to reveal himself at all, but trick the waker into making the wishes. Only in the first 2 movies did the djinn have to take souls to fix/charge the stone first, and in all first 3 movies the waker recieved psychic visions of the djinn's victims, but in this movie that did not happen.
So was it part of the djinn's wish-granting powers to force the waker to see each death happen , or was it kind of an error in this film for the waker to not have visions ?
