"But you do see something they can't. Even if I hadn't come, you'd see, wouldn't you?" The crone hadn't said a thing about the ring, and for now, she wouldn't. She had to save that particular reveal until later; she wasn't sure that the dark one would understand. It was possible that he'd see it as some sort of betrayal, perhaps not to himself but to her husband.
"You'd have felt it. That this is more than just a show of power. You'd know that this is power. Things were done here that were stronger and darker than those silly police would or could understand. You've felt it before, and you'd recognize it again, wouldn't you?" She stepped in closer, her hand guiding his to rest at her back. Her free hand now resting open on his chest, right over his heart.
"You'd seen it at work, and you know the signs. Even if your visit was so very brief. You came to it because you had to know if you'd feel it again, didn't you?" She didn't know if this were true, but the thing within might want to know. The thing within knew of the power in blood and death, pain and sex. It knew all the dark little corners of power, and it could use them. Was it still in there? Had it guided Dexter here to test and taste?
