And We know that Rumple had voices in his head (more than just Neal during 3b).
Did the original Dark One suffer similarly? And why do you think that the DarkOne chooses to interact with the current dark one in this way?
Most likely to get the current host to embrace the Darkness by slowly unravelling their psyche. It's sorta like how the First Evil from Buffy operates; play with the victims' mind and coerce them into doing what it wants.
