Of course, this Harker who entered the room first was no other than Harker 2.0.
He laid in bed. "Looks like he's too busy at the moment. Lucky bastard. But at least he wasn't able to look into what I was doing with his other buddies."
He thought about the taste of Joan's lips and soft skin, biting his own finger hard until it drew blood. He moaned at the thought of tasting the blood of that woman instead.
Harker would never have anticipated that the clone he created wasn't really the exact replica of him. Sure they were the same physically and mentally. But holistically speaking, Harker 2.0 was his more instinctual side.
It was the side of him that dreamed of ravishing and feeding on Joan. It was the side of him that every so often comes up to feel joy at the pain of others.
